The roots of a polynomial equation are the values of x that you can plug in so the function is equal to 0. To find the roots, you would want to factor the polynomial and set the factored form equal to zero. 

1) First factor the polynomial. The factored form of  is (x + a)(x + b), where a and b are two numbers that multiply to -72 and add up to 1. By testing numbers that are factors of -72, you can find that 8 x 9 = 72, meaning that either 8 or 9 has to be negative to get -72. But which one of those is negative?

Since you want the two numbers to add up to 1, that means 9 must be positive and 8 must be negative, since -8 + 9 = 1! That makes a and b, 9 and -8. Your factored form would be (x - 8)(x + 9) = 0.

2) Now you want to find values of x where the function is equal to 0. Remember that anything multiplied by 0 is equal to zero. That means you can set each factor, (x - 8) and (x + 9), equal to 0 to find the two values of x (aka the roots)!
Factor 1:x - 8 = 0x = 8
Factor 2:x + 9 = 0x = -9
Your two roots are 8 and -9.

Answer: 8 and -9

3.<br>June has 248 oranges. She sells of these oranges. How many oranges did June sell?<br>Answer.​
uranmaximum [27]

Answer:

93. Divide 248 by 8. One eighth of 248 = 31.

June sold 3/8 of the 248 oranges.

If 1/8 = 31 and June sold 3/8 of the oranges.

Multiply 3 × 31. Therefore June sold 93 oranges.

If 32 % of a is 1.12 then what is the value of a?
alukav5142 [94]

Answer:

4.5 is the value of A

Step-by-step explanation:

do it doing part/whole and cross crossing :)

32/100 because it’s a percentage and 1.12/x. 1.12 times 100 to get 112, and then 32 times x = 32x. your equation right now is 32x = 112, bur we want to get rid of that x, so we are going to divide 112/32 to get the whole of 3.5 for the value of A.

What is the area of the trapezoid?
tensa zangetsu [6.8K]

Answer:

24 square units

Step-by-step explanation:

For Trapezoid

a = 8

b = 4

h = 4

Area of Trapezoid

<em><u>A = a + b/2 * h</u></em>

= 8 + 4/2 * 4

= 12/2 *4

= 6 * 4

= 24

Thus, the area of the trapezoid is <em><u>24 square units</u></em>
