What is the value of x so the rectangles have the same area. a. 12 & X b. X-2 & 16

Mathematics

The area of a rectangle is <em>L x W</em>. We have to get the value of x first so that we can find the area of the rectangle.

To get the value of x
given:
<span>a. 12 & X
b. X-2 & 16 </span>
solution:
12x (x) = (8-2 ) 16
12x = 16x-32
32 = 16x-- 12x
<u>32 </u> = <u>4x</u>
4        4
8 = x

Checking:

a. 12 & X                                                          b. X-2 & 16
Area of a rectangle = L x W                            Area of a rectangle  = L x W
                                =12 x 8                                                             =  (8-2) 16
Area of a rectangle = 96                                                                  = 6 (16)
                                                                        Area of a rectangle  = 96

What is the equation of the line that passes through the point (8,-2) and has an undefined slope?
Aleksandr-060686 [28]

Answer:

x = 8

Step-by-step explanation:

A line with an undefined slope is a vertical line parallel to the y- axis, with equation

x = c ( c is the value of the x- coordinates the line passes through )

The line passes through (8, - 2) with x- coordinate 8 , thus

x = 8 ← equation of line

PLEASE HELP
s344n2d4d5 [400]
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1
