X=2
To check it you plug in 2 for x. Which then gives you:
3+(2-14)=-15+6 which then gives you:
3+-12=-15+6 which the gives you:
-9=-9
Rectangle A and B.
rectangle B is 8x12 and if you divide 8 and 12 by 4 you get 2x3
(7 - 4n) x 6 is the same as 6(7 - 4n)
Expand to become:
6(7) + 6(- 4n)
42 - 24n is your answer.
A=L*W
L=W+5
A=(W+5)W
500=W²+5W
W²+5W-500=0
W=(-5+/-√(25+4*500))/2=(-5+/-√2025)/2=(-5+/-45)/2
we are going to take only positive value, so W=(-5+45)/2=20
L=W+5=20+5=25
W=20,
L=25
