Answer:
x = -5, 7
Step-by-step explanation:
Step 1: Write equation
x² - 2x - 35 = 0
Step 2: Solve for x
Factor: (x - 7)(x + 5) = 0
Find roots: x = -5, 7
Step 3: Check
Plug in x to verify if it's a solution.
(-5)² - 2(-5) - 35 = 0
25 + 10 - 35 = 0
35 - 35 = 0
0 = 0
7² - 2(7) - 35 = 0
49 - 14 - 35 = 0
35 - 35 = 0
0 = 0

2/3 times what equals 24?
The number 24 is 2/3 times of the number 36.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the fine operations performed on them.
Variables are the name given to these symbols because they warrant set values. We constantly observe constant change in specific values in our day- to- day situations. But the need to depict these shifting values is ongoing.
In order to determine the values, these symbols are also subordinated to colorful addition, deduction, addition, and division computation operations.
We have to find 2/3 times what equals 24.
let the number be x.
So, 2/3 of x = 24.
2x/ 3 = 24
2x = 72
x= 72/ 2
x= 36
Thus, the required number is 36.

The ratio of two complementary angles is 5:4. Find the measure of both angles.
Answer:
50 degrees and 40 degrees
Step-by-step explanation:
50 degrees and 40 degrees
complimentary = add up to 90 degrees
5:4:9
50:40:90
Answer:
50° and 40°
Step-by-step explanation:
Complementary angles sum to 90°
sum the parts of the ratio, 5 + 5 = 9 parts
divide 90 by 9 for the value of one part of the ratio
90° ÷ 9 = 10° ← value of 1 part of the ratio, thus
5 parts = 5 × 10° = 50°
4 parts = 4 × 10° = 40°
The 2 angles are 50° and 40°

6(2x - 6) = -7(-2x + 4)
Answer:
Step-by-step explanation:
Simplifying
6(2x + -6) = -7(-2x + 4)
Reorder the terms:
6(-6 + 2x) = -7(-2x + 4)
(-6 * 6 + 2x * 6) = -7(-2x + 4)
(-36 + 12x) = -7(-2x + 4)
Reorder the terms:
-36 + 12x = -7(4 + -2x)
-36 + 12x = (4 * -7 + -2x * -7)
-36 + 12x = (-28 + 14x)
Solving
-36 + 12x = -28 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation.
-36 + 12x + -14x = -28 + 14x + -14x
Combine like terms: 12x + -14x = -2x
-36 + -2x = -28 + 14x + -14x
Combine like terms: 14x + -14x = 0
-36 + -2x = -28 + 0
-36 + -2x = -28
Add '36' to each side of the equation.
-36 + 36 + -2x = -28 + 36
Combine like terms: -36 + 36 = 0
0 + -2x = -28 + 36
-2x = -28 + 36
Combine like terms: -28 + 36 = 8
-2x = 8
Divide each side by '-2'.
