Sum of the number and its of inverse equals 0.
Answer: 50
Find the area of the triangles then multiply by 2.
1/2 x 5 x 10 = 25
25 x 2 = 50
Answer:
The width cannot be negative, so w = 9, l = 16.
Step-by-step explanation:
w = the width
l = w +7
A = l · w
A= w ( w + 7 )
144 = w2 + 7w
0 = w2 + 7w - 144
0 = ( w - 9 )( w + 16 )
The width cannot be negative, so w = 9, l = 16.
(4x-6)/3=8
4x-6=24
4x=30
x=7.5 or x=30/4
