20
This is because
2x+(6x+20)=180
8x+20=180
8x=160
8x/8=160/8
X=20
150/15=10
because 10 times 15 equals 150
3 digit dividend = 150
divisor between 10 and 20 is 15

Answer:
Yes, they started with equal expressions.
Step-by-step explanation:
To simplify Vanessa's expression, we must rationalize the denominator. This means we must make the denominator x.
We need to multiply the denominator by x^(1/6) to make a whole x; this means we must multiply the numerator by x^(1/6) as well:
Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula
225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P =
P= 56.89202
So measure of angle P is 57 degrees
