Answer:
The difference of 6 times x subtracted from 8 is equal to the sum of 4 added to Twice x
Answer:
Simplifying
6x + -3 = 21 + -2x
Reorder the terms:
-3 + 6x = 21 + -2x
Solving
-3 + 6x = 21 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
-3 + 6x + 2x = 21 + -2x + 2x
Combine like terms: 6x + 2x = 8x
-3 + 8x = 21 + -2x + 2x
Combine like terms: -2x + 2x = 0
-3 + 8x = 21 + 0
-3 + 8x = 21
Add '3' to each side of the equation.
-3 + 3 + 8x = 21 + 3
Combine like terms: -3 + 3 = 0
0 + 8x = 21 + 3
8x = 21 + 3
Combine like terms: 21 + 3 = 24
8x = 24
Divide each side by '8'.
x = 3
Simplifying
x = 3
Step-by-step explanation:
70 is the area of the polygon
Answer:
12 feet
Step-by-step explanation:
Since the side length is a length, it will be positive and not negative, so we solve this equation for s by taking the positive square root of both sides of the equation. We get that s = 12, so the side length of a square with an area of 144 square feet is 12 feet.While -12 is "a square root" of 144, the square root operation here denotes a function from nonnegative real numbers to nonnegative real numbers. A function can only produce a single result. So the expression √144 evaluates to the positive root 12.Because one square foot is 144 square inches, divide the total number of square inches by 144.
