Answer:
the correct answer is 4
Step-by-step explanation:
y = x^2 + x - 5
y = 4^2 + 4 - 5
y= 16 + 4 -5
y = 15
Answer:

Step-by-step explanation:
So the point-slope formula looks like this: 
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
Set 7b as a common factor and put it outside the parentheses:
7b(x+y)
Check:
7b(x+y)
Distribute the 7b
7bx+7by
Hope this helps.
The error that Kevin made was he did not include two units (see the circled areas) while counting the units. He counted the units there as one instead of two at those junctions. The correct measure of the perimeter of the figure is 20 units.
