Answer:
V = a²b³ + acb² units³
Step-by-step explanation:
The volume of a rectangular prism is given by :
V = l×b×h
Here, l = b² units
b = aunits
h = ab+c units
So, the volume of the prism is given by :
V = b² × a × (ab+c)
= ab²(ab+c)
= a²b³ + acb²
Hence, the required volume is a²b³ + acb² units³.
Answer:
the midpoint is (9,5). hope this helps
You can do this in parts.
g(-3) = 3(-3) + 1 = -9 + 1 = -8
So, 5g(-3) = 5(-8) = -40.
So f(-1) + 5g(-3) = 2 - 40 = -38
Or you can do this as one big chunk.
f(-1) + 5g(-3)
![=[(-1)^2+1] + 5[3(-3) + 1] \\ = (2) + 5(-9 + 1) \\ = 2 + 5(-8) \\ = 2 - 40 \\ = -38](https://tex.z-dn.net/?f=%3D%5B%28-1%29%5E2%2B1%5D%20%2B%205%5B3%28-3%29%20%2B%201%5D%20%5C%5C%0A%3D%20%282%29%20%2B%205%28-9%20%2B%201%29%20%5C%5C%0A%3D%202%20%2B%205%28-8%29%20%5C%5C%0A%3D%202%20-%2040%20%5C%5C%20%3D%20-38)

area of a rectangle = length × width
area = (2x + 3)(x - 4) ( expand using FOIL )
= 2x² - 8x + 3x - 12 = 2x² - 5x - 12 → D
