Y = 1/5x - 2
Perimeter = 2(x + y)
P = 2(x + 1/5x - 2)
<span>P = 12/5x - 4</span>
Answer:
B and D
Step-by-step explanation:
A simplifies to a linear equation
C is a cubic
The other 2 are quadratic and can be solve using the formula
One of the numbers are negative
Remember this... a negative divided by a positive will result in a negative and a negative divided by a negative will result in a positive, the same goes for multiplication
15x+40=115
15x+40-40=115-40
15x=75
15/15 x=75/15
x= 5
