Answer:
The slope of the perpendicular line is -1/4
Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
Let the slope of the perpendicular line have sloe p
m*p = -1
4 * p = -1
Divide each side by 4
p = -1/4
The slope of the perpendicular line is -1/4

Let the height of the building be H. So:


Make H the subject

Associative property: When the numbers inside of the parenthesis change with the outside in order to change the expression.
Distributive: When the number on the outside of the parenthesis are distributed with the numbers on the inside of the parenthesis.
Commutative: Numbers that are switched around randomly to change the expression.
Additive inverse: It is like zero pairs, when a positive number is made neutral by adding the same number but negative. Or a positive to a negative. Ex: 23+-23=0.
Slope is 4/5
Points are (3,6)
Your first point should be (3,6) then from that point go up 4 and 5 to the right, that should be your second point, then graph.
Answer:
L=6x^2-4x+5
P=12x^2-4x-2
Step-by-step explanation:
A=WL
So, we know the area is 6x^2-8x-30 and the width is 2x-6
Substitute
(6x^2-8x-30)=(2x-6)(L)
L=(6x^2-8x-30)/(2x-6
Divide
L=6x^2-4x+5
P=2L+2W
Substitute
P=2(6x^2-4x+5)+2(2x-6)
P=12×^2-8x+10+4x-12
Simplify
P=12x^2-4x-2
