W = L - 7
WL = 78
(L-7)L = 78
L^2 - 7L - 78 = 0
Factorize: (L-13)(L+6) = 0
L = 13 or -6
A length cannot be negative, so the length must be 13 miles.
The width is 13-7 = 6 miles.
Answer: the width is 66
Step-by-step explanation: see if 87m is the width then you add it twice it equals 174 then you subtract it from 306m which equals 132 but since theres two sides you divide it to get 66 Hope this help happy Easter!! c:
They both have the same rate of change
Answer:
x = 6
Step-by-step explanation:
Alternate angles are congruent.
7x - 9 = 3x + 15 {Subtract 3x form both sides}
7x - 3x -9 = 15
4x - 9=15 {Add 9 to both sides}
4x = 15+9
4x = 24
x = 24/4
x = 6
This is complicated because I’m typing on a phone, but
