N + n + 3 + 2n = (sum of age)
First change the problem and add 1 in front of the variables (n)
1n + 1n + 3 + 2n = (sum of age)
Next add the like terms which are 1n, 1n, and 2n
1n + 1n = 2n
2n + 2n = 4n
Now 3 is left by itself add it to the problem
4n + 3
SIMPLIFIED EXPRESSION IS 4n + 3

Answer:
8.66 ft
Step-by-step explanation:
A square is a shape that has an equivalent length and breadth across it’s cross section.
What this means is that measuring the length across the top and bottom will yield the same length value.
Thus, mathematically, let’s call the measured height h
The square of this height gives the area
thus;
h^2 = 75
h = √75
h = 8.660254037844
This is approximately 8.7 to one decimal place
Answer:
The length of the pipe = 17 feet
Step-by-step explanation:
length = 15 feet
width = 8 feet
Pythagorean theorem,
(diagonal)² = (length)² +(width)² {all angles of rectangle are 90°}
= 15² + 8²
= 225 + 64 = 289
diagonal = √289 = √ 17 * 17
= 17 feet
