Simplify the following expression: (3x+4)(x-1)(x-3)
Answer:
3x³ - 8x² - 7x + 12
Step-by-step explanation:
We multiply these terms, (so expand the brackets). Referring to the diagram attached, we multiply the first terms, outer terms, inner terms, and last terms.
Let's first look at the first two (we will do something about the third brackets later):
(3x+4)(x-1)
Firsts:
3x²
Outer:
-3x
Inner:
4x
Last:
-4
Now we combine:
3x² - 3x + 4x - 4
= 3x² + x - 4
So from the whole equation, we now have this:
(3x² + x - 4)(x - 3)
We do a similar thing here.
3x³ - 9x² + x² - 3x - 4x + 12
Simplify:
3x³ - 8x² - 7x + 12

2 - 3x = -x - 8 Solve for X
Answer:
X=5
Step-by-step explanation:
(step 1) 2 - 3x = -x - 8
-3x + 2 = -x -8
(step 2)
-3x + 2 = -x - 8
-3 + 2 - 2 = -x -8 -2
(step 3)
-3x = -x- 10
(step 4)
-3 + x = -x -10 +x

What is an angle?When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.
Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.
As per the side angle side rule, the correct way to prove that the triangles are congruent is ∠ ABC ≅ ∠ DEF. Therefore, option D is correct.

Write the equation for the following graph (Hint: y= mx + b) Write the slope as a simplified fraction, not a decimal. Please Help
Answer:
y = (-5/2)x + 1
Step-by-step explanation:
We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

5x − 8( 1 + 7x ) = −8
Answer:
x = 0
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
5x - 8(1 + 7x) = -8
Step 2: Solve for x
Distribute -8: 5x - 8 - 56x = -8Combine like terms: -51x - 8 = -8Isolate x term: -51x = 0Isolate x: x = 0Step 3: Check
Plug in x into the original equation to verify it is a solution.
Substitute in x: 5(0) - 8(1 + 7(0)) = -8Multiply: 0 - 8(1 + 0) = -8Add: -8(1) = -8Multiply: -8 = -8Here we see that -8 does indeed equal -8.
∴ x = 0 is a solution of the equation.
Is the point (-18, 31) on the line y = -0.5x + 22?
Answer:
Yes
Step-by-step explanation:
Remember: (x, y)
Substitute the coordinates to the variables (x and y):
Equation: y = -0.5x + 22
Substitution: 31 = -0.5(-18) + 22
31 = 9 + 22?
Correct! The coordinates substituted to its variables solve and make the equation make sense!

Answer:
18x-16
Step-by-step explanation:
expression: (11x-8)+7(x-1)
ok so what you want to do is combine like terms
but first you are going to distribute
(11x-8)+(7x-8) you distribute the 7
they you can subtract 8 from -8 and that will give you -16
you will then add 11x and 7x which will get you 18x
the final expression will be 18x-16
1) You are taking a Tae Kwon Do class that costs $15 a month. In addition, you needed to
purchase a uniform. You paid a total of $108 after 6 months. Write an equation that glves
the total cost (in dollars) as a function of the length of time you have been taking classes
(in months). Find the total cost after 9 months.
Answer:
$162
Step-by-step explanation:
you divide 6 months by 2 then you divide 108 by 2 then you add the half of 108 and plus it to 108 then you get your total.
The function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135
What is unit rate?A unit rate means a rate for one of something.
Given that, You are taking a TAE Kwan Do class that costs $15 a month. In addition, you needed to purchase a uniform. You paid a total of $108 after 6 months.
We have unit rate = $15 per month
Since, one month cost is $15 therefore, for 6 months = 15×6 = $90
Therefore, cost of uniform = $108 - $90 = $18
Let you are taking classes for x months, the function of the length of time you have been taking classes,
f(x) = 15x
For 9 month cost =
f(9) = 15×9 = 135
Hence, the function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

A ski hat is priced at $19.50 and a pair of ski boots are priced at $85.50. If the sales tax rate is 7%, then what is the total cost of the ski hat and ski boots ?
Answer:
The total cost of the ski hat and the ski boots is $112.35.
Step-by-step explanation:
First, we need to add the prices of the ski hat and the ski boots.
85.50 + 19.50 = $105
Now, we need to find 7% of $105, and then add it to the total.
105 x 0.07 = $7.35
105 + 7.35 = $112.35
Therefore, the total cost of the ski hat and the ski boots is $112.35.
Hope this helps! :D
