Answer: (b - 4)(b - 3); b = 4 and 3

Step-by-step explanation:

ima assume these are exponents since you didnt care to correctly write the equation.

What two numbers multiply to equal 12, but add to equal -7? That's -4 and -3

So the factored form of this trinomial is (b - 4)(b - 3) = 0. Make each of these expressions equal to 0 in order to get your answer.

Answer: A) and B)

Step-by-step explanation:

So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.

The second one you find the distance it moves each second.

You do this by distance over time d/t. Then you divide the 408 by that number.

So 264cm / 11 seconds = 24 cm/sec

Then 408cm/ 24cm per sec = 17s

1. Convert each fraction to a decimal.
DerKrebs [107]
3/4 = 75/100 = 0.75

0.75 is a terminated decimal (does not continue forever)

0.75 is a rational number (it is a decimal)

1/3 = 33.33.../100

0.333333.... is a continuing decimal, and so it is a repeating decimal

1/3 is a repeating number

20 to 25 percent change
inna [77]
A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

Hope this helps :)

f(3) = -2(3)^2 - 4

f(3) = -2(9) - 4

f(3) = -18 - 4

f(3) = -22
