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.
By solving the equation:
4b + 6 = -2
4b = -2 - 6 (taking 6 from each side)
4b = -8
b = -2 (divide both sides by 4)
Answer:
Step-by-step explanation:
As 4 is accumulated by thousands place
And ones place is 4 into 2/twice
And hundreds place accumulates zero
And tens place is 4 - 0=4
The no is
4048
Answer:
/2 and /4 because angle 1 is 90
