Answer:

(x - 10)(x + 7).

Step-by-step explanation:

This is a quadratic expression  and the factors are of the form (x + a)(x + b).

We have x^2 - 3x - 70.

- to find the values of a and b  in this expression we need 2 numbers whose product is -70 and whose sum is -3.

They are -10 and +7 , so the factors are:

Square PQRS is drawn inside rectangle ABCD such that side PQ is on side AB and side SR is on side DC, as shown below. Line segment PB is 17 inches long and line segment DR is 15 inches long. What is the perimeter of rectangle ABCD?

Answers

The perimeter of the rectangle ABCD is the sum of its side lengths, and the perimeter is 70 inches

How to determine the perimeter of ABCD?

The question is incomplete, as the figure of the square and the rectangle are not given; so I will give a general explanation

The perimeter (P) of the rectangle ABCD is calculated using:

P = AB + BC + CD + DA

Since the opposite sides are equal, the formula becomes

P = 2 * (AB + BC)

Assume that the values of AB and BC are 20 and 15, respectively;

The equation becomes

P = 2 * (20 + 15)

Evaluate the product

P = 70

Hence, the perimeter of the rectangle ABCD is 70 inches (using the assumed values)

9. You are installing a swimming pool. Write a polynomial that represents the area of the walkway
8 ft width of the pool
(6x-4) ft length (of the pool)
(2x + 6) ft length of the Walk way
10x ft width of the Walk way

Answers

Answer:

  (10x² +12x +32) ft²

Step-by-step explanation:

The area of the walkway around the pool is the difference between the area of the entire rectangle, and the area of the pool. The area of each rectangle is found by multiplying its length and width.

__

Overall area:

  ((2x +6) ft) × (10x) ft = (10x² +60x) ft²

Pool area:

  ((6x -4) ft) × (8 ft) = (48x -32) ft²

Walkway area:

  overall area - pool area = ((10x² +60x) ft²) -((48x -32) ft²)

  = (10x² +12x +32) ft²
