A) 2L + 2W = 48
B) L * W = 140
B) W = 140 / L
Inputting this to equation A)
A) 2L + 2*(140 /L) = 48
L + 140/L = 24
Multiplying both sides by "L"
L² + 140 = 24L
L² -24L +140 = 0
(L -10) * (L-14) = 0
L= 10
L = 14
If length = 10 then width =14
If length = 14 then width = 10
Answer:
the first blank is 9 and the second is 8. when you switch the numbers in the equation the answer will still be the same. hope this was helpful!
Answer:
Step-by-step explanation:
x² + x - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1) = (x-1)(x+2)
8x² + 4x = 4x ( 2x + 1)
3x² + 10x + 8 = 3x² + 6x + 4x + 4*2 =3x * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)
