Answer:
-6
Step-by-step explanation:
Equation for length:
l = 3w
l × w = 12
Substitute 3w into L.
(3w) × w = 12
4w = 12
w = 3
Substitute 3 into w to find the length.
l = 3w
l = 3×3
l = 9
The width is 3 and the length is 9.
Answer:
y=6x-2 is perpendicular to the 6y=-x+7
y=6x+1 is parallel to the y=6x-2
Step-by-step explanation:
if product of two lines gradient is -1 than lines are perpendicular
gr y=6x-2
y=mx+c m=gradient
1)m=6
2)m=-1/6
3)m=6
if gradients of 2 lines are equal they are paralel
Answer: 34
f(-2) means inserting 'x = -2' into the equation.
x = -2
4*|-2 -4| +2
= 4*|-8| + 2
= 4*8 + 2
= 32 + 2
= 34
