Question 1: 1 and 4 is alternate interior angles
Question 2: 4 and 8
Question 3: 1 and 5
Question 4: 110 degrees (they are corresponding angles, which means that they have the same degree)
Question 5: angle 10 is 129, 180 - 129 = 51. measurement of angle 12 is 51

hope this helps

Evaluate this expression <br> (-7--9)*(8+2)

Marizza181 [45]

Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.

P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

Knowing this, we should start by doing the equations <em>within </em>each parentheses.

$(-7 - -9) *(8 + 2)$
$(2) *(10)$

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

$(2)*(10) = 20$

20 is the answer.

Please solve the following quadratic equation and show your work: x^2 -x =30

saveliy_v [14]

Rewriting the equation as a quadratic equation equal to zero:
x^2 - x - 30 = 0
We need two numbers whose sum is -1 and whose product is -30. In this case, it would have to be 5 and -6. Therefore we can also write our equation in the factored form
(x + 5)(x - 6) = 0
Now we have a product of two expressions that is equal to zero, which means any x value that makes either (x + 5) or (x - 6) zero will make their product zero.
x + 5 = 0 => x = -5
x - 6 = 0 => x = 6
Therefore, our solutions are x = -5 and x = 6.

You need to replace the molding around a floor that is 15 feet long and 23 feet 6 inches wide. The molding sells for $0.50 per f

julsineya [31]

$41.04 you multiply how long and how wide it is together. after that that the answer is 2,070 then divide it by 50 and you get $41.04.

i hope that helps!!

Terri is rewriting 7 to the 13th power in expanded form. How many factors should she use in her expression?

Pachacha [2.7K]

13

Because the exponent is really just how many factors you have.
For example 2 to the power 5 would have 5 factors in expanded form.
