Answer:
A
B
Step-by-step explanation:
The right side of the numbers line includes the positive numbers
We need to write out algebraic equations to describe the information we have, then solve them using substitution.
We will define length as a and width as b.
we know that a x b = 1600 cm3 (area = length x width)
and a=4b
So, we can substitute the vaule 4b for a in the first equation:
4b x b = 1600
we can simplify to 4b2 = 1600
divide both sides by 4:
b2 = 400
take the square root of each side:
b = √400
b=20
So we know the width = 20
length = 4 x width = 80
Equivalent ways of stating this expression are
![(6561)^{0.25}=6561^{ \frac{1}{4} }= \sqrt[4]{6561}](https://tex.z-dn.net/?f=%286561%29%5E%7B0.25%7D%3D6561%5E%7B%20%5Cfrac%7B1%7D%7B4%7D%20%7D%3D%20%5Csqrt%5B4%5D%7B6561%7D%20)
I used a calculator to simplify and got 9.
This is true because
