Answer: See below

Step-by-step explanation:

a) 6(3x+4y-8)

Use the distributive property:

6*3x + 6*4y - 6*8

18x + 24y - 48

So D is the correct answer

b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.

12+4x

= 4(3+x)

So D is the correct answer

c) When you expand both C and D and simplify, you get 16x+36 as solution

d) 14x+2y+10z

Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times

14x+2y+10z

= 2(7x+y+5z)

So D is the correct answer again ;)

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

$(5x)+(23+90-18)=180$
$5x+95=180$

Step 2: Subtract 95 from both sides.

$5x+95-95=180-95$
$5x=85$

Step 3: Divide both sides by 5.

$5x/5=85/5$
$x=17$

Step 4: Check if solution is correct.

$(5*17-18)+23+90=180$
$67+23+90=180$
$180=180$

Thus, x = 17.
