Answer: D
Step-by-step explanation: -12*3= 36x
-3/4*-12 = +9 so, D
2 times the length of the midsegment equals the length of the base. That being said, your equation will be 2(x+21)=x+32.
First, use the distributive property on 2(x+21). You are left with 2x+42=x+32.
Subtract x from both sides. You are left with x+42=32.
Finally, subtract 42 from both sides of the equation. You are left with your answer: x=-10.
Check your work: -10+21=11 and -10+32=22
11 is half of 22.
Answer:
Please, see the image below.
Step-by-step explanation:
I attached an image of the sketched region below.
You take into account that y=0 is the x axis.
Furthermore, you take into account that f(x)=-5x^3 is, for x=-2 and x=-1:
f(-2)=40
f(-1)=5
Finally, the region bounded by the equations is above the negative x axis.
1/3 full is your answer. :D
