Answer:
<u>1.</u> 20 boxes cost $36. The unit rate is 1:1.8 and when you multiply 1.8 by 5 you get 9. If you also multiply 1.8 by 20 you get 36.
<u>2.</u>He completes 12.5 pages in 200 minutes.
200 divided by 32
multiply that answer by 2
which is 12.5.
hope it helps!

Answer:
a. 2
b. -1 or 2
Step-by-step explanation:
When the funtion h(x) is at 0, or h(0), the y value is visibly shown to be at 2. When the function's y-value is at -2, you need to find the x values which make that the case. You can see that at x=-1, the y value is at -2, making this our first value. You can also see the function meet -2 when x =2, making this the second value. Hope this helps!
I graphed the vertices and got a triangle but its very hard to solve its perimeter. Therefore, I identified right triangles to help me solve for the perimeter making each side the hypotenuse of each right triangle.
Pythagorean Theorem: a² + b² = c²
a = short leg ; b = long leg ; c = hypotenuse
P(0,0) ; R(-3,4)
a = 3 ; b = 4 ;
3² + 4² = c²
9 + 16 = c²
25 = c²
√25 = √c²
5 = c
P(0,0) ; Q(8,6)
a = 6 ; b = 8
6² + 8² = c²
36 + 64 = c²
100 = c²
√100 = √c²
10 = c
Q(8,6) ; R(-3,4)
a = 2 ; b = 11
2² + 11² = c²
4 + 121 = c²
125 = c²
√125 = √c²
11.18 = c
Perimeter = 5 + 10 + 11.18 = 26.18
