Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
Answer:
58
Step-by-step explanation:
If the X is times
10+ 54/9 X 8
10+6*8
10+48= 58
Answer:
A
Step-by-step explanation:
There is a point 12,5 and it makes the most sense
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:
![y = 3x-8](https://tex.z-dn.net/?f=y%20%3D%203x-8)
Thus, we have to:![m = 3\\b = -8](https://tex.z-dn.net/?f=m%20%3D%203%5C%5Cb%20%3D%20-8)
Therefore, the given equation is of the slope-intersection form.
Answer:
Option B
Answer:
x = 25.5
Step-by-step explanation:
suppose RS and MQ are parallel the sum of angle MRS and RMN would be 180 degrees
2x + x + x 78 = 180 add like terms then subtract 78 from both sides
4x = 102 divide both sides by 4
x = 25.5
