What is x find it please! Two questions 15 and 18
Let other 2 angles be d
44 + 2d = 180°
(sum of triangle)
2d = 180 -44
2d = 136
d = 136/2
d = 68
x = 68 + 44 (exterior angle is equal to sum of interior opposite angles)
x = 112°
l
2. part
let the other angles be d
3d = 180° (sum of angles of triangle)
d = 60°
x = 60 + 60
x = 120°

Answer:
(5x^2-6)*(2x-7)
Step-by-step explanation:
1.(((10 • (x3)) - (5•7x2)) - 12x) + 42
2.(((2•5x3) - (5•7x2)) - 12x) + 42
3. 10x3-35x2-12x+42 is not a perfect cube
4.Factoring: 10x3-35x2-12x+42
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -12x+42
Group 2: 10x3-35x2
Pull out from each group separately :
Group 1: (2x-7) • (-6)
Group 2: (2x-7) • (5x2)
-------------------
Add up the two groups :
(2x-7) • (5x2-6)
5. Factoring: 5x2-6
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
= (5x2 - 6) • (2x - 7)

How many solutions does the system have? {y=−2x 2y=x2−3x Enter your answer in the box.
By solving given equation and then finding discriminant we get that this system of equations have 2 solutions
What is system of equations?Collection of two or more equations with a same set of unknowns is called system of equations.
Given equation
[tex]$$y=-2 x+2\ \ ...(1)\\\\y=x^{2}-3 x$$\ \ \ ...(2)[/tex]
From equation (1) and (2)
[tex]x^{2}-3 x=-2 x+2\\\\x^{2}-3 x+2 x-2=0\\\\x^{2}-x-2=0[/tex]
This is a quadratic equation
So discriminant
[tex]D=b^2-4ac[/tex]
[tex]D=(-1)^2-4(1)(-2)\\D=1+8\\D=9[/tex]
As D is >0 so we will get two values of x
and two values of y corresponding to values of x
By solving given equation and then finding discriminant we get that this system of equations have 2 solutions

Find the domain of the graphed function.
Answer:
D. 2 ≤ x ≤ 5
The domain is the x values of the graph.
Here, we have points with x values at 2 and 5. Since the function stays within these two points, our domain is;
D. 2 ≤ x ≤ 5
We always use the y values as the range of a function on a graph while x values gives us the Domain . So , by looking at the above graph we can say that , [tex]{\pmb{\bf x \in [2,5]}}[/tex] or can further written as [tex]{\bf 2\leq x\leq 5}[/tex] .
Henceforth , Option D) [tex]{\bf 2\leq x\leq 5}[/tex] is correct

Sophie buys milk and vegetables at the grocery store. She spends $3.29 on milk and has a total bill of $15.56. Write and solve an equation to determine how much Sophie spent on the vegetables.
Answer: $12.27
Step-by-step explanation:
She spent a total of $15.56
Vegetables cost $12.27
Milk cost $3.29
Subtract the total bill by the amount of the milk and you have the total for the vegetables which is $12.27

6) An expression is given.
X2+zx-12
The expression can be written as (x+q) (x+r) where q, r, and z are integers.
What are possible integer values or q, r, and z?
Expressions are mathematical statements without the equation sign
The possible integer values of q, r, and z are 3, -4 and -1
How to determine the values of the integersThe expressions are given as:
x^2 + zx - 12
(x + q)(x + r)
Both expressions are equal.
So, we have:
[tex]x^2 + zx - 12 = (x + q)(x + r)[/tex]
Expand
[tex]x^2 + zx - 12 = x^2 + (q + r)x + rq[/tex]
By comparison, we have:
[tex]q + r = z[/tex]
[tex]rq = -12[/tex]
Assume that q = 3.
So, we have:
[tex]3r = -12[/tex]
Divide by 3
[tex]r = -4[/tex]
Recall that:
[tex]q + r = z[/tex]
So, we have:
[tex]z = 3 -4[/tex]
[tex]z = -1[/tex]
Hence, the possible integer values of q, r, and z are 3, -4 and -1

If Janelle originally started 575
miles from Mammoth Lakes and continues traveling at the same rate (from part (a)), how many more hours will it take her to arrive at her destination?
Given that Janelle travels at 65 mph. the number of more hours it will
take her to reach her destination is approximately 5 hours.
How can the time to reach her destination be calculated?Possible part of the question that appear missing are;
The distance Janelle drove in 4 hours = 260 miles
The distance from which she started = 575 miles
Required:
The number of extra hours it will take her to reach her destination
Solution:
The remaining distance = 575 miles - 260 miles = 315 miles
[tex]Speed = \mathbf{ \dfrac{Distance}{Time}}[/tex]
[tex]Janelle's \ average \ speed = \dfrac{260 \, miles }{4 \, hours} = \mathbf{ 65 \, mph}[/tex]
[tex]Time = \dfrac{Distance}{Speed}[/tex]
Which gives;
[tex]Time \ to \ reach \ her \ destination = \dfrac{315 \, miles}{65 \, mph} = 4\frac{11}{13} \, hours \approx \mathbf{ 5 \, hours}[/tex]
The time it takes Janelle to reach her destination ≈ 5 hours

Answer: $27 for four large pizzas is cheaper than 32$ for five large pizzas
Step-by-step explanation:
Answer:
$32 for 5 pizzas
Step-by-step explanation:
Assuming you're trying to determine which option is the better deal, the first step would be to determine the price per pizza.
Option 1: $27 for 4 pizzas
$27 / 4 pizzas = $6.75 per pizza
Option 2: $32 for 5 pizzas
$32 / 5 pizzas = $6.40 per pizza
Option 2 is the better deal because each pizza costs less.

Square ABCD is similar to square EFGH. The ratio of AB:EF is 1:4. The area of square EFGH is 14,000ft^2. What is AB?
Answer: 5sqrt(35)
Step-by-step explanation:
If the ratio of the side lengths is 1:4, since the ratio of the areas is the square of the ratio of the side lengths, the ratio of the areas is 1:16.
This means the area of square ABCD is 14000/16 = 875.
Therefore, AB=sqrt(875)=5sqrt(35).
