Answer:
a. x = 8
b. m<B = 140
Step-by-step explanation:
a.
m<A = m<B
40 = 5x
x = 8
b.
m<A + m<B = 180
m<B = 180 - m<A
m<B = 180 - 40
m<B = 140
Expression for perimeter is 2(14-x + x) = 28
<u>Step-by-step explanation:</u>
Step 1:
Given expression for area of the rectangle = a(x) = x(14-x) where x is the width. Then length = 14-x since area = length × width
Step 2:
Find expression for perimeter of the rectangle.
Perimeter of the rectangle = 2(length + width) = 2(14 - x + x) = 2 × 14 = 28
Answer:
A.
Step-by-step explanation:
The equation for slope intercept form is simply
y = mx + b
in your problem m = -1/3
and b which is the y intercept = to 8/3
So A. is the answer
Hope this helps!
Answer:
Parallel lines are lines <u>in the same plane</u> that do not intersect, like lines on notebook paper.
The "in the same plane" requirement is important! Take a look at the attached image. Lines AD and DC don't intersect, but they are <u>not</u> in the same plane (face of the rectangular solid). We don't call those parallel, we call them skew lines.
