Answer:
5(2+y)
Step-by-step explanation:
The sum of 2 and y = 2+y
So,
5 times the sum of 2 and y(2 + y) = 5 × (2+y) = 5(2+y)
The answer is 5(2+y)
Answer:
65
Step-by-step explanation:
let the son's age be x then the man's age is 5x
In 13 years
son's age = x + 13 and man's age = 5x + 13 and he is 3 times as old as son
5x + 13 = 3(x + 13)
5x + 13 = 3x + 39 ( subtract 3x from both sides )
2x + 13 = 39 ( subtract 13 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13 ← son's present age
5x = 5 × 13 = 65 ← man's present age

Answer:
Even if a right solid became oblique, the volume would not change, because the cross sectional area and height would remain the same. Therefore, by Cavalieri's principle, the volume is the same as the original solid.
Step-by-step explanation:
sample answer
If it i set up like this just multiply the opposite corners.
<u /><u>k</u> = <u>32</u>
7 56
So multiply k * 56 and multiply 7 * 32.
Now you should have 56K = 224.
To solve for K, divide both sides by 56 to get K by itself.
Final Answer: K=4.
