16)
=(x+2)(x+1)
cause
(x+2)(x+1) = x^2 + 2x + x + 2
= x^2 + 3x + 2
answer
(x+2)(x+1)
Answer:
x=12
Step-by-step explanation:
Since AB=BD, they have equal length. 15x+4=2x+160, 13x=156, x=12
34x+95=3(14x+9)
We move all terms to the left:
34x+95-(3(14x+9))=0
We calculate terms in parentheses: -(3(14x+9)), so:
3(14x+9)
We multiply parentheses
42x+27
Back to the equation:
-(42x+27)
We get rid of parentheses
34x-42x-27+95=0
We add all the numbers together, and all the variables
-8x+68=0
We move all terms containing x to the left, all other terms to the right
-8x=-68
x=-68/-8
x=8+1/2
