Answer:

-2x^4 + 11x^3 + 30x^2 - 29x - 10

Step-by-step explanation:

1. Use the Distributive Property

(2x^2 + 3x - 5)(-x^2 + 7x + 2)

2. Remove parenthesis

2x^2(-x^2 + 7x + 2) + 3x(-x^7x+2) - 5(-x^2 + 7x + 2)

3. Collect like terms

-2x^4 + 14x^3 + 4x^2 - 3x^3 + 21x^2 + 6x + 5x^2 - 35x - 10

4. -2x^4 + 11x^3 + 30x^2 - 29x - 10

Phoebe usually drives to work each day on a 12-mile road that is currently closed for construction. While the road is closed she
Mumz [18]

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles

<h3>What is a Pythagoras theorem?</h3>

The square of the longest side is equal to the square of the sum of the othersides.

Before we can calculate the total distance, we will need to get the hypotenuse on  both sides using the Pythagoras theorem as shown:

H^2= 12^2 + 9^2

H² = 144 + 81

H² = 225

H = 15

For the other hypotenuse

h² = 12² + 5²

h² = 144 + 25

h²  = 169

h = 13 mils

The total distance = 5 + 15 + 9 + 13

The total distance = 42 miles

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles
