Answer: I believe x = 105

Step-by-step explanation: When you add a triangles angles, you should get 180. The straight is equal to 180 degrees

Step 1: 180 - 55 - 50 = 75

Step 2: 180 - 75 = 105

Answer:

X=105

Step-by-step explanation:

Add angles

55+50 = 105

subtract from 180

180-105 = 75

it’s consecutive angles so subtract from 180

180-75 = 105

Footlocker in the mall is having a 25% off sale on all tennis shoes. Joe paid $67.50 for his
marta [7]

Answer:

The original price of the shoes was $90.

Step-by-step explanation:

25% off means the price Joe paid for it is 75% of the original price.

Set up an equation:

75/100 = 67.50/x

Cross multiply

75 × x = 100 × 67.50

75x = 6750

x = 90

Check our work:

First solve for 25% off of 90 (our answer).

25% = 0.25

90 × 0.25 = 22.50

Next, subtract the discount from 90.

90 - 22.50 = 67.50

67.50 was what Joe paid so this is correct.

You are told that a third powered polynomial has zeroes at -1, 2, 5.
vichka [17]

Answer:

a) factors of polynomial are: (x+1)(x-2)(x-5)

b) the required polynomial in standard form is: \mathbf{x^3-6x^2+3x+10}

Step-by-step explanation:

The polynomial has zeros at -1,2,5

Part A) Write the three factors of the polynomial

we have x=-1, x=2 and x=5 as zeros of polynomial

so factors will be:

(x+1)=0, (x-2)=0, (x-5)=0

So, factors of polynomial are: (x+1)(x-2)(x-5)

Part B) Write the polynomial in standard form

For finding polynomial, we will multiply all the factors i.e

(x+1)(x-2)(x-5)

(x+1)(x-2)(x-5)\\=(x(x-2)+1(x-2))(x-5)\\=(x^2-2x+x-2)(x-5)\\=(x^2-x-2)(x-5)\\=x(x^2-x-2)-5(x^2-x-2)\\=x^3-x^2-2x-5x^2+5x+10\\=x^3-x^2-5x^2+5x-2x+10\\=x^3-6x^2+3x+10

So, the required polynomial in standard form is: x^3-6x^2+3x+10
