9x^2 -6x +1+12=0
9x^2 -6x +13=0
factorise
(3x-1)(3x-1) =0
so, x= 1/3
Hi Horizonwill,
I am trying to helps you and I just want to say, the answers you can eliminate is B, C, and D. So it is leaving you with A
Hope This Helps

Answer:
6
Step-by-step explanation:
Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
Answer:42, 3, 2, 15
