Answer 2x^3+9
Explanation: evaluate the exponent
9+4^2/8•x^3
9+16/8•x^3
Divide the numbers
9+16/8•x^3
9+2x^3
Rearrange terms
9+2x^3
2x^3+9 and that’s the answer;)
The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
Answer:
It's 398
Step-by-step explanation.
Diameter of 8.
height of 12.
8 - .75 - .75= 6.5
6.5/2 = 3.25
3.25 x 3.25 x 12 x 3.14 = 397.995
round to the nearest whole number and you get
398
Take the diameter (8) an subtract is by both sides of the walls (0.75 each wall) that gives you 6.5. Take that 6.5 and half that, because you need to have the radius to solve volume problems, giving you 3.25. Then multiply 3.25 by 3.25 together ( I know it seems redundant but it just works easier this way) This gives you 10.5625. After that take 10.5625 then multiply it into 12, being the height, which gives you 126.75. Finally take 126.75 and multiply that into 3.14 (pie) giving you the answer.

Answer:
f(3) = -13
Step-by-step explanation:
f(x)= - x²-4 (not (-x)²)
f(3) = - 3² - 4 = - 9 - 4 = -13
