width (w) = w
Length (L) = 3w - 10
Area (A) = L x w
77 = (3w - 10)w
77 = 3w² - 10w
0 = 3w² - 10w - 77
0 = 3w² - 21w + 11w - 77
0 = 3w(w - 7) + 11(w - 7)
0 = (3w + 11)(w - 7)
0 = 3w + 11, 0 = w - 7
w = 
, w = 7 (width cannot be negative!)
w = 7
Length (L) = 3w - 10 = 3(7) - 10 = 21 - 10 = 11
Answer: width = 7 ft, Length = 11 ft
Answer:yes
Step-by-step explanation:
You have to simplify each equation
7m +6 - 5 = 15 2m + 5 = 9
7m + 1 = 15 2m = 4
7m = 14 m = 2
M = 2
They both end up with the same answer so they are equivalent
<u>Supplementary:</u> N and M
<em>Supplementary angles: </em>A pair of angles that when combined are equal to 180°.
<u>Vertical:</u> M and I
<em>Vertical angles: </em>A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
<em>Complimentary angles: </em>A pair of angles that when combined are equal to 90°.
Hope this helps! Good luck! :D
