A - a removes both a’s from equation, then you’re left with b + bsquared, since they are unknown values you cannot combine them, even if it is the same letter, you can only add and subtract unknown values with their same letters together.
Try to count your square and use the formula lxwxh
I don’t know the answer but Don’t try to open that link. I’ve seen a lot of people using it. Stay safe:)
Y=mx+b
Slope is m
Y intercept is b
So it's-4
Standard form of a linear equation is :
Ax + By = C
Given:
<span>y = 1/6x + 5
Rearranging,
(1/6)x - y = -5
Multiplying whole equation by 6.
x - 6y = -30
or
-x + 6y = 30
Hope it helps!</span>
