4.4 is the correct answer, hope this helps!
Area = Length * Width = l * w
l = x + 2
w = 2x - 5
Area = (x + 2)(2x - 5) = 56
Area = 2x^2 -x - 10 = 56
Area = 2x^2 - x - 66 = 0 Now you have to factor this thing.
Area = (2x + 11)( x - 6) = 0 This is more or less done by guessing.
2x + 11 = 0 can't work. x would be negative.
x - 6 = 0
x = 6.
Check
=====
l = x + 2
l = 6 + 2
l = 8
w = 2*x - 5
w = 2*6 - 5
w = 12 - 5
w = 7
l*w = 8*7 = 56. It checks.
If this is the best answer you get, could you consider a Brainly? I need 2 of them to move up.
Answer: i will put the answer as a comment but what are you rounding to
Step-by-step explanation:
Answer:
Width Length
5 8.7
7.9 11.6
9 12.7
11.3 15.0
13 16.7
Step-by-step explanation:
If they gave you the width, you add 3.7 to get the length.
If they gave you the length, you subtract 3.7 to get the width.
