Answer:

<h2>B. 3xy − 4x</h2>

Step-by-step explanation:

step one:

Given the expression  13x(9y – 12) we are expected to expand the expression to obtain a similar expression given in the options

step two

we proceed by

= 13x(9y-12)\\\\=(117xy-156x)

step three

we proceed to both terms in the expression

bt a common factor which is 39

\frac{117xy}{39}-\frac{156x}{39}

3xy-4x

Answer: 125

Step-by-step explanation: ∠4 and 55 are supplementary angles. This means that ∠4 and 55 add up to 180. We can use this to solve for ∠4.

180 - 55 = ∠4

125 = ∠4

So, ∠4 is equal to 125 degrees.

Find the value of x.. is the answer 103? if not how do you figure it our
scoundrel [369]

The angle diagonal to 103° is equal to 103°.  So here's your equation:

(103+14x+7)°=180°

So now you can simplify:

110°+14x=180°

now subtract 110 on both sides

14x=70°

now divide by 14 on both sides

so the answer is x=5°

hope this helps
