Answer:
-4x^2+7x
Step-by-step explanation:
Multiply -4x+7 and x.
You get -4x^2+7x.
Hello :)
Slope intercept form: y = mx+b
Perpendicular: forms a right angle (90°)
We are asked to write the linear equation (written in slope intercept form) that passes through (-2,-11) and is perpendicular to
to do this we need to find the perpendicular line using the point.
Step 1: use the point slope formula: to find the line perpendicular to
m=4; we got 4 because we were supposed to find the negative reciprocal of the slope of the original line by multiplying -(1/4) by (-1).
y=4x-3
we can check this by seeing that when we graph it, the line passes through (-2,-11) , and it is also perpendicular to

Answer:
P = 27.2c-7.2d
Step-by-step explanation:
It is given that,
The width of a rectangle is (8.3c-8.4d)
The length of a rectangle is (5.3c+4.8d)
The perimeter of a rectangle is equal to the sum of its all sides i.e.
P = 2(l+b)
P = 2(8.3c-8.4d+5.3c+4.8d)
P = 2[(8.3c+5.3c)+(4.8d-8.4d)]
P = 2(13.6c-3.6d)
⇒P = 27.2c-7.2d
Hence, the expression that represents the perimeter of the rectangle is 27.2c-7.2d.

Step-by-step explanation:
You want to make sure the building is insured so that if there is a disaster, you can get your money back. You also want to insure your most valuable contents, too, but you probably already have them insured.
