Answer:
39x-7
Step-by-step explanation:
The perimeter is all the sides added together so
9x + 8x - 2 + 5x + 1 + 17x - 6
Since you can't solve it you just want to simplify the equation, add the like terms together
9x+8x+5x+17x = 39x
-2+1-6 = -7
Your equation is 39x-7
(f+g)(x)=0
f (x) + g (x)=0
now,
substitute their values
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
Um idk sorry lol that’s way to hard for me
Answer:
16
Step-by-step explanation:
Simply plug in 2 for a, then 6 for b and substitute
(2+6)2
Then do order of operations to simplify PEMDAS
First what's inside the parenthesis
(8)2
Then multiply
16.
