Answer:
2(x + 10)
Step-by-step explanation:
The perimeter is all the sides added together so you times the length by 2, (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) add them together
16 + 2x + 4
2x + 20
take out the highest common factor of 2
2(x + 10)
Answer:
y = -5x + 6
Step-by-step explanation:
y = 1/5 x + 4/5
so that two lines are perpendicular, its slope must be opposite and reciprocal
y = m x + b
m: slope perpendicular -1/m
if our formula is y = 1/5 x + 4/5
m = 1/5
so the slope of our new formula will be
m' = -5/1
m' = -5
now if you tell us that you have to go through a certain point (1/1)
we just have to replace the values in the following formula and solve
y - y1 = m ( x - x1)
y - 1 = -5 ( x - 1)
y = -5x + 5 + 1
y = -5x + 6
3(x + 5) - 2(x + 2) = 20
1. y = 2x
y=2x+1
2 . x =5
y = -4
3. y = x+6
y -6 =x
4 . y= 3x+ 4
y =3
