Answer: (B)35

Step-by-step explanation: the ratio of the lengths of the first rectangle compared to the length of the second is 30:25, or 6:5. Do the same for the width. the first rectangle has a width of 42. divide it by 6, (according to the ratio) which is 7. then multiply it by 5 (also according to the ratio) and you get 35. Hope this helps.

Which is a solution to (x − 2)(x + 10) = 13?x = 3

x = 8

x = 10

x = 11

Answers

The solution to the given algebraic expression (x - 2)(x + 10) = 13 is x = 3

What is an algebraic equation?

An algebraic equation is the combination of variables and their coefficients(usually numbers) with arithmetic operations. The main purpose of an algebraic expression is to determine the value(s) of the variable(s).

From the given information:

(x - 2)(x + 10) = 13

x² + 10x - 2x - 20 = 13

x² + 8x -20 -13

x² + 8x - 33 = 0 (quadratic equation)

Using the quadratic formula, the values of x are - 11 and 3. Since we are considering only the positive integer only, x = 3

Answer: X=3

Step-by-step explanation:

1. expand the equation

x^2 + 10x -2x -20 = 13

2. Collect like terms

x^2 + 8x - 20 = 13

3. Simplify

x^2 + 8x = 13 + 20

x^2 + 8x = 33

x^2 = 33 - 8x

4. Substitute answers for guess and check

3^2 = 33 - (8 x 3)

9 = 33 - 24

This equation is correct therefore x = 3
