Step-by-step explanation:
Multiply by the reciprocal, also sometimes referred to as "Keep, Change, Flip." Here is how it works. You rewrite the division question as a multiplication question by flipping the second fraction over. Next, keep the first number, change the division to multiplication and then flip the second fraction over.
Answer: distributing
2(6x + 6) <em>is</em> 12x + 12
16x - 8 <em>is</em> 8(2x - 1)
3(x - 2) <em>is</em> 3x - 6
3(4x + 4) <em>is</em> 12x + 12
2x + 6 <em>is</em> 2(x + 3)
4(x + 3)<em> is</em> 12x + 12
Step-by-step explanation:
Distribute the number in front of the parenthesis to the numbers inside the parenthesis .
for example: 3(x-2)
3 times x = 3x
3 times -2= -6
answer: 3x - 6
Answer:
B :)
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
<> sum of the interior angles of the polygon is (8-2)*180 = 1080°
<> since all the lengths are equal it implies all the angles are equal
<> there are 8 angles
=> 8(16x + 23) = 1080
=> 16x + 23 = 135
=> 16x = 135 - 23
=> 16x = 112
=> x = 112/16
=> x = 7
