Answer:
The length is 15 and the width is 10
Step-by-step explanation:
Let l = length
w = l-5
We know the area is 150
A = l*w
150 = l ( l-5)
150 = l^2 - 5l
Subtract 150 from each side
0 = l^2 - 5l - 150
Factor
0= ( l+10) ( l-15)
Using the zero product property
l+10 =0 l-15=0
l = -10 l = 15
Since we cannot have a negative length
l = 15
w = 15-5 = 10
The length is 15 and the width is 10
Answer:
11.75
Step-by-step explanation:
Interior angles in a quadrilateral sum to 360.
Opposite angles in a parallelogram are the same.
360=118+118+(4x+15)+(4x+15)
= 236 + 8x + 30
= 266 + 8x
8x = 360 - 266 = 94
x=94/8 = 11.75
