3(x+1)=3x+3
-2(x-1)+6=-2x+2+6=-2x+8
3x+3=-2x+8
X=1 because 3(1)+3=6 and -2(1)+8=6
C 13 to get from -9 to 4 first you have to go 9 units to the right to get to 0 then 4 more to get to four and 9 + 4 = 13.
You need to multiply by the reciprocal, aka multiply the fraction by the cube root.
Answer: IT IS BBBB
Step-by-step explanation:
In the figure attached, the complete question is shown.
Originally the scale is 1 inch: 12 yards, the width is 6 inches, that is, 6*12 = 72 yards, and the length is 9 yards, that is, 9*12 = 108 yards
If the scale is 1 inch: 36 yards, then 72 yards are:
1 inch / x inches = 36 yards / 72 yards
x = 72/36 = 2 inches
which represents the new width.
And 108 yards are:
1 inch / x inches = 36 yards / 108 yards
x = 108/36 = 3 inches
which represents the new length.
Answer: SECOND OPTION
Step-by-step explanation:
Given the following equation:
![x^2-36=5x](https://tex.z-dn.net/?f=x%5E2-36%3D5x)
You can follow these steps in order to find the values of "x" that makes the equation true:
1. Subtract
from both sides of the equation:
![x^2-36-5x=5x-5x\\\\x^2-5x-36=0](https://tex.z-dn.net/?f=x%5E2-36-5x%3D5x-5x%5C%5C%5C%5Cx%5E2-5x-36%3D0)
2. Factor the equation. Find two numbers whose sum be -5 and whose product be -36. These are 4 and -9:
![(x+4)(x-9)=0](https://tex.z-dn.net/?f=%28x%2B4%29%28x-9%29%3D0)
Then you get:
![x_1=-4\\\\x_2=9](https://tex.z-dn.net/?f=x_1%3D-4%5C%5C%5C%5Cx_2%3D9)
Checking:
![(-4)^2-36=5(-4)\\\\-20=-20](https://tex.z-dn.net/?f=%28-4%29%5E2-36%3D5%28-4%29%5C%5C%5C%5C-20%3D-20)
