Answer:
g = -2
Step-by-step explanation:
g = -5r + 13
r = 3
You substitute three for r in the equation.
--------------------------------------------------------------
g = -5(3) + 13
--------------------------------------------------------------
Distribute -5 to 3
--------------------------------------------------------------
g = -15 + 13
--------------------------------------------------------------
Solve
-------------------------------------------------------------
g = -15 + 13
-15 + 13 = -2
g = -2
B. Sometimes because in learned that it isn't always that way.
6x + x + x - 5 - 2 = 8 + 2x + x
combine like terms
8x -7 = 8 +3x
subtract 3x from each side
5x -7 = 8
add 7 to each side
5x = 15
divide by 5
x=3
Answer: 8x -7 = 8 +3x
x=3

80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
you then would have to find 2 numbers that would add up to make 42.
When you try 16*2+5*2= 32+10= 42 cm as your perimeter.
16*5= 80 cm^2 as your area.
