To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Answer:
Step-by-step explanation:
1) Angle mnq is equal to angle q plus angle n (because two interior angles equal one exterior angle)
2) 132= 54 plus angle n
3) 180-132=48 (angles on a straight line equal to 180 degrees)
3x+102=180
3x= 78
x is 26 degrees
D = 2m - 4 (Dad's age is 4 less than twice Mark's)
m + d = 95 (their ages total 95)
We have a value for d, so plug it in:
m + 2m - 4 = 95
Simplify:
3m - 4 = 95
Add 4 to both sides:
3m = 99
Divide by 3:
m = 33
