Answer:

x = ±2sqrt(2)

Step-by-step explanation:

x^2 = 8

Take the square root of each side

sqrt(x^2) = ±sqrt(8)

x = ±sqrt(4*2)

We know that sqrt(ab) = sqrt(a)sqrt(b)

x = ±sqrt(4)sqrt(2)

x = ±2sqrt(2)

Lines a and b in the figure above are parallel. What is the value of p?

It will be c- 20:
4q and 2(q+30) have to equal the same therefore q=30 which makes both these equations equal.
3p + 4q then have to equal 180 as they are on a straight line so you know q=30 so 4x30=120 so 180-120=60
Then 60/3=20 and that is your answer.
Hope this helps :)
