5in=20ft
divide both sides by 5
1in=4ft
Answer:
x = - 5, x = 7
Step-by-step explanation:
Given
x² - 2x - 35 = 0
Consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (- 2)
The factors are - 7 and + 5, since
- 7 × 5 = - 35 and - 7 + 5 = - 2, thus
(x - 7)(x + 5) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 7 = 0 ⇒ x = 7

Answer: 10
Step-by-step explanation Simplifying
2x + 7 = 3(x + -1)
Reorder the terms:
7 + 2x = 3(x + -1)
Reorder the terms:
7 + 2x = 3(-1 + x)
7 + 2x = (-1 * 3 + x * 3)
7 + 2x = (-3 + 3x)
Solving
7 + 2x = -3 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 2x + -3x = -3 + 3x + -3x
Combine like terms: 2x + -3x = -1x
7 + -1x = -3 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + -1x = -3 + 0
7 + -1x = -3
Add '-7' to each side of the equation.
7 + -7 + -1x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + -1x = -3 + -7
-1x = -3 + -7
Combine like terms: -3 + -7 = -10
-1x = -10
Divide each side by '-1'.
x = 10
Simplifying
x = 10
