We found the y-intercept, so now we plug it in it's right full spot in the formula.

Answer:

Step-by-step explanation:

[pay attention to the signs :)

Answer:
perimeter you add all sides together:
5x+2 +5x+2 +x +8 +x+8
12x +20
and for Area you multiply:
(x + 8)(5x + 2)
5x^2 + 2x + 40x +16
5x^2 +42x +16
so your answer is the first one or "A"
250 = 5 x is the equation you can use
Pennies Toby has = 178
Pennies Bella has = 190
Hence, Bella has more pennies by 190-178=12
Bella has 12 more pennies than Toby.
