Hello again Charlesbabegirl! :)

First of all, let's say that the sum of all internal angles of a triangle is always 180°

This means that if you add up angles A, B and C you get 180 but we should find first the value of x by setting up a proportion of this type:

A + B + C = 180

12x + 12 + 15 + 3x + 18 = 180

Move all the known terms (those that don't have x) to the right with changed sign.

12x + 3x = 180 - 12 - 15 - 18

15x = 135

Divide both terms by 15

x = 9

Then plug the value of x...

m∠A = 12(9) + 12 = 108+12 = 120°

m∠C = 3(9) + 18 = 27 + 18 = 45°

Hope I helped and let me know if I was right!

The area of a rectangle is 32a^3b^4 square units. The length is 4a^2b. Find the width. show your work
kaheart [24]

Answer:

The answer to your question is width = 8ab³

Step-by-step explanation:

Data

Area = 32a³b⁴ u²

length = 4a²b   u

Formula

Area of a rectangle = width x length

Solve for width

                           width = \frac{Area}{length}

Substitution

                          width = \frac{32a^{3}b^{4}}{4a^{2}b}

Simplify using rules of exponents, just remember that in a division we subtract the exponents and divide the coefficients normally.

                          width = 8 a²b³

Marsha pays $25 each month for a car wash membership. Which of the following represents the total amount subtracted from her acc
Kipish [7]

The correct amount taken from the account for car wash membership fee is shown below:

−4|25| = −$100

What is the amount subtracted from the account on the account balance?

The amount subtracted has a negative impact on the account balance because it reduces the account balance as it is an expense or debit transaction unlike a credit that increases the balance

$25 is spent every month, which means -$25 taken from the account every month

total amount deducted for 4 months=4*-$25

total amount deducted for 4 months=-$100

The correct option which indicates -$100 is −4|25| = −$100
