Answer:
The expression for the given value of the variable d=75 is, 135
Step-by-step explanation:
Given the expression:
....[1]
We have to find the value for the given expression when d = 75
Substitute the value of d in [1] we have
![2(75)+\sqrt[3]{-45(75)}](https://tex.z-dn.net/?f=2%2875%29%2B%5Csqrt%5B3%5D%7B-45%2875%29%7D)
⇒ ![150+\sqrt[3]{-3375}](https://tex.z-dn.net/?f=150%2B%5Csqrt%5B3%5D%7B-3375%7D)
⇒
Simplify:
⇒
Therefore, the expression for the given value of the variable d=75 is, 135
Answer:
Yes
Step-by-step explanation:
What is the question we need to answer? We got the information
If we look at his calculations
2((9)(20) is the front an back rectangle
2((9)(34)) is the side rectangles
(34)(20) is the bottom
2(1/2(20(24)) is te front and top triangles
and the last one assumes that they are triangles which is incorrect
answer is D
D
use the formula speed = wavelength x wave frequency
