Answer:

  6x^2 -2x

Step-by-step explanation:

As written, the constant terms in the first factor cancel each other. The distributive property is used to perform the multiplication:

  (3x^2 +1 -1 -x)(2) = (3x^2 -x)(2) = (3x^2)(2) -x(2)

  = 6x^2 -2x

Point P is the interior of LaTeX: \angle OZQ.\:∠ O Z Q .If LaTeX: m\:\angle\:OZQ\:m ∠ O Z Q= 125 and LaTeX: m\angle OZP\:m ∠ O Z
saw5 [17]

Answer:

<h2>∠PZQ = 63°</h2>

Step-by-step explanation:

If point P is the interior of ∠OZQ , then the mathematical operation is true;

∠OZP +  ∠PZQ =  ∠OZQ

Given parameters

∠OZQ = 125°

∠OZP = 62°

Required

∠PZQ

TO get  ∠PZQ, we will substitute the given parameters into the expression above as shown

∠OZP +  ∠PZQ =  ∠OZQ

62° +  ∠PZQ = 125°

subtract 62° from both sides

62° +  ∠PZQ - 62° = 125° - 62°

∠PZQ = 125° - 62°

∠PZQ = 63°

<em>Hence the value of ∠PZQ  is 63°</em>

Find the measure of angle 1.
WITCHER [35]

Answer:

108°

Step-by-step explanation:

x = 9

So x + 63° = 72°

So is 8x

So 8x = 72°

Multiply 72° by 2

144°

Now subtract 144° from 360°

The answer is 216°

Now divide by 2

108°

Hope this helped :)

PLEASE HELP!!!!!!
Grace [21]

Answer:

x = 8/3 and y = 32/3

Step-by-step explanation:

Add the two equations, getting -3y = -32, thus y = 32/3

Sub for y in first equation, getting 5x + 32/3 = 24

5x = 40/3

x = 8/3
