Multiply the expressions below. Then simplify if possible. a. 2x(3x – 4) b. (x+3)(2x-5) C. (2x + 5)(2x – 5) d. X(2x + 1)(x-3)
Answers
Answer:
a) 6x² - 8x
b) 2x² + x - 15
c) 4x² - 25
d) 2x³ + 7x² - 3x
Step-by-step explanation:
a) 2x (3x - 4)
brackets means multiplication or into
base on the question
2x * 3x = 6x^2
and
2x * (-4) = -8x
therefore
6x² - 8x
is the answer
b) (x + 3) (2x - 5)
clear brackets with (x + 3)
i. x * (2x - 5) = 2x^2 - 5x
ii. +3 * (2x - 5) = 6x - 15
add i add ii
2x² - 5x + 6x - 15
if u noticed, there are similar figures 6x and 5x, so we take like term
2x² + x - 15 answer
c) (2x + 5) (2x - 5)
clear bracket
i. 2x * (2x - 5) = 4x² - 10x
ii. 5 * (2x - 5) = 10x - 25
add i and ii
4x² - 10x + 10x - 25
collect terms
4x² - 25 answer
d) x (2x + 1) (x - 3)
I) first we deal with x(2x+1)
x * (2x + 1) = (2x² + x)
II) then we find the multiplication of
(2x² + x) (x - 3)
i. 2x² * (x - 3) = 2x³ - 6x²
ii. x * (x - 3) = x² - 3x
add i and ii
2x³ - 6x² + x² - 3x
collect terms
2x³ - 5x² - 3x

Find the exact value of the remaining trigonometric functions given: Tan x = Undefined Sin x > 0
(I’ve been having some trouble understanding this one—please explain, if possible!)
Answers
Answer:
sin(x) = 1cos(x) = 0cot(x) = 0csc(x) = 1sec(x) = undefinedStep-by-step explanation:
The tangent function can be considered to be the ratio of the sine and cosine functions:
tan(x) = sin(x)/cos(x)
It will be undefined where cos(x) = 0. The values of x where that occurs are odd multiples of π. The smallest such multiple is x=π/2. The value of the sine function there is positive: sin(π/2) = 1.
The corresponding trig function values are ...
tan(x) = undefined (where sin(x) >0)
sin(x) = 1
cos(x) = 0
__
And the reciprocal function values at x=π/2 are ...
cot(x) = 0 . . . . . . 1/tan(x)
csc(x) = 1 . . . . . . .1/sin(x)
sec(x) = undefined . . . . . 1/cos(x)

We are given with a circle and we need to find the equation of the circle , but first let's recall that , the equation of a circle with radius 'r' and centre at (h,k) is given by [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex]
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here (h,k) = (0,0) .Which means that the centre is located at the point whose coordinates are (0,0) which is also known as origin . Now , finding the equation of the circle :-

Which expression represents the product of 3 and (n + 1.8) ?
A 5.55
B 9.15n
C 3.75 + 1.8
D 3.75 + 5.4
Answers
Answer:
D
Step-by-step explanation:
it is a strange question. but I guess its meaning is to identify an expression that is structured in the same way as the generic basic expression.
3×(n + 1.8)
after doing the multiplication this gives us
3n + 3×1.8 = 3n + 5.4
so, the only answer option including 5.4 is D.
it would mean that 3n = 3.75. n = 1.25
but just to show you how strange this question is, let's have a look at the other answer options :
is 5.55 = 3n + 5.4 ?
it would mean
0.15 = 3n
n = 0.05
so, formally, this is also an expression that represents the original expression.
9.15n = 3n + 5.4
6.15n = 5.4
n = 5.4/6.15 = 0.87804878...
so, formally, this is also an expression that represents the original expression.
3.75 + 1.8 = 3n + 5.4
5.55 = 3n + 5.4
and we are back to A and therefore, formally, this is also an expression that represents the original expression.
so, many greetings from me to your teacher. he/she has to be more careful about how to phrase questions.
because here, formally, all 4 answers are theoretically correct.
An architect creates a scale model of a building with a scale of 5 cm =4 m. If the actual building is 32 m tall, how tall is the scale model?
A.8
B.25.6
C.33
D.40
Answers
The height of the building on the scale model created by the architect is 40 centimeters long.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
The architect creates a scale model of a building with a scale of,
[tex]\rm 5 \;cm =4 \; m[/tex]
As, one meter is equal to 100 centimeters. Thus, the scale factor used by the architect for the building is,
[tex]r=\dfrac{5}{400}\\r=\dfrac{1}{80}[/tex]
Now the actual building is 32 m tall. Let suppose the height of the building on the model is x meters. Thus, the scale factor for this can be given as,
[tex]r=\dfrac{x}{3200}[/tex]
Now, both the scale factor are of the same model. Therefore,
[tex]\dfrac{x}{3200}=\dfrac{1}{80}\\x=40\rm cm[/tex]
Hence, the height of the building on the scale model created by the architect is 40 centimeters long.

Nate found that the least common multiple is 48.
One of these students made a mistake.
Which student made a mistake?
What number should the student have found instead?
Answers
Answer:
Nate made a mistake. He should have got 24 as Least common factor.
Step-by-step explanation:
Given number are 8 and 12.
To find the GCF or LCF we have to list multiples.
For LCF
List the multiples of each number until at least one of the multiples appears on all lists.Find the smallest number that is on all of the lists.This number is the LCM.For GCF
List the multiples of each number until at least one of the multiples appears on all lists.Find the Biggest number that is on all of the lists.This number is the GCFThe least common multiple of 8 and 12 is 24.
The Greatest common multiply of 8 and 12 is 4.
Hence, Nate is wrong. Nate should have found 24.

Cross off the outer most values 16 and 30 to end up with this smaller set

Then repeat to get this smaller set
23,24
We add up these numbers and divide the sum by 2

The median is 23.5

a) For AQMNO use the Triangle Proportionality Theorem to solve for x. OMN
Answers
Answer:
x = 12 unitsperimeter = 113 unitsGiven for big triangle:
MN = 36MO = 3x + 9 + 15 = 3x + 24Given for small triangle:
side 1 : 36 - 9 = 27side 2 : 3x + 9setting up proportionality:
[tex]\hookrightarrow \sf \dfrac{36}{3x+24} = \dfrac{27}{3x+9}[/tex]
[tex]\hookrightarrow \sf 36(3x+9) = 27(3x+24)[/tex]
[tex]\hookrightarrow \sf 108x+324 = 81x+648[/tex]
[tex]\hookrightarrow \sf 108x-81x = 648-324[/tex]
[tex]\hookrightarrow \sf 27x = 324[/tex]
[tex]\hookrightarrow \sf x = 12[/tex]
Perimeter of the triangle:
36 + 17 + 15 + 3x + 9
36 + 17 + 15 + 3(12) + 9
113 units
Answer:
x = 12
perimeter = 113 units
Step-by-step explanation:
Triangle Proportionality Theorem states that if a line parallel to one side of the triangle intersects the other two sides, then it divides the sides into proportional corresponding segments.
[tex]\implies 3x+9 : 15 = (36-9) : 9[/tex]
[tex]\implies 3x+9 : 15 = 27 : 9[/tex]
[tex]\implies \dfrac{3x+9}{15}= \dfrac{27}{9}[/tex]
[tex]\implies 3x+9 = 45[/tex]
[tex]\implies 3x = 36[/tex]
[tex]\implies x = 12[/tex]
Perimeter = [tex]3x+9 + 15 + 17 + 36[/tex]
Substituting [tex]x = 12[/tex]:
⇒ perimeter = 3(12) + 9 + 15 + 17 + 36
