2x^2+3. the 2x cancel out and the rest is combining like terms
Answer:
3x - 13 +58 = 90, so 3x +45 = 90
Then 3x = 90 - 45 = 45 and x= 45/3 = 15.
m∠MNQ = 3x-13 = 3(15) - 13
= 45-13
= 32
Answer:

Step-by-step explanation:
Answer:
The cost for 20 students would be $120
Step-by-step explanation:
We know that 4x5=20 therefore we will multiply 30x4 which will give us 120.
Our final answer would be $120
7,500 - 4,170 = 3,330
sea level (0) - 3,330 = -3,330
It is 3,330 meters below sea level.
It is 1,670 meters away from the base of the mountain.
