Answer:
6 and 15
Step-by-step explanation:
n1 + n2 = 21
2(n1) + 3 = n2
n1 = 6
n2 = 15
6 + 15 = 21
Answer:
16
Step-by-step explanation:
<em>Greetings from Brasil...</em>
According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>
It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²
