Need help, please explain the answer

Mathematics
1 answer:
stellarik [79]3 years ago
7 0

Answer:

7 - x meters

Step-by-step explanation:

This is a difference of squares. The formula for difference of squares is

a^2-b^2 = (a-b)(a+b)

So plug the numbers we know into this formula.

Area = lw

49 - x^2 = (a-b)(7+x)

49 - x^2 = (7-x)(7+x)

<u>The length is 7 - x meters.</u>

Yuri [45]
Amount of Interest (I) = P * R * T /100

Solve for w<br> 7=-4w+7<br> w=
devlian [24]

Answer:

0

Step-by-step explanation:

If I'm not mistaken, the answer must be 0.

7-7 is 0, that cancels out

0 divided by -4w is zero. That leaves w alone

w=0. I think that's the answer.
