Build a bond ladder to boost

Someone help me please with this algebra problem
Ann [662]

Answer:

7 in.

Step-by-step explanation:

2L + 2W = 16

Try L = 7

2(7) + 2W = 16

14 + 2W = 16

2W = 2

W = 1

If the length is 7 in., then the width is 1 in. That is perfectly acceptable, so L = 7 in. is a good value.

Try L = 8

2(8) + 2W = 16

16 + 2W = 16

2W = 0

W = 0

A length of 8 would make a width of 0. You can't have a rectangle with 0 width, so L = 8 does not work.

When L = 9 or L = 10, the width would be negative. The width of a rectangle cannot be a negative number, so these values doe not work.

Answer: 7 in.

Can someone help asap?<br> What is the length of red segment EC to the nearest tenth?
oksano4ka [1.4K]
First you find the length of the green rectangle by using a^2 + b^2 = c^2
So that means 4^2 + 7^2 = length of green
That equals 8.1 when you square root it.
Then, you use 8.1^2 + 3^2 (which is the green rectangle height) to find the red line using the same equation
So your answer is 8.6 cm.
