X^2+4x-12=0
(x+6)(x-2)=0
X can equal -6 and 2.
x=-6
x=2
Answer:
x+2x+2=17
Step-by-step explanation:
I'm assuming that's what you're asking, so here is the answer explanation.
3x+6=21
3x=15
Hence, x=5
Apply x=5 to x+2x=2
5+10+2
=17
This is cheating. You aren’t allowed to ask for help strate out.
A - 36 = B
B = 76 - A * 2.
the number is 40.
A = 40
:D
Perimeter (P) = 2L + x
4900 = 2L + x ⇒ 4900 - x = 2L ⇒
= L
Area (A) = L · x
A = (
) (x)
=
