Please write that as 60^(1/2) for greater clarity.
Our job here is to find the largest perfect square factor of 60. Note that 60 = 4*15; 4 is a perfect square, but 15 is not.
Thus, 60^(1/2) = 2sqrt(15).
Answer: 416 Portraits total.
Step-by-step explanation:
So this is actually a really simple question.
There a four cafeteria walls right? And if she puts 104 on each of them, it's a simple mathematical equation.
MATH:
4 x 104 = 416
Hope this helps!
Answer:
C. 3
Step-by-step explanation:
8 / 1/3
When dividing fractions, do CCF (Copy, Change, Flip)
You keep the first number: 8
Change the division sign to multiplication: X
Flip the fraction to make it its reciprocal: 3/1
New expression:
8 X 3/1 or 8 X 3
Answer:
x = 2 - 5
, x = 2 + 5
Step-by-step explanation:
x² - 4x = 71
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = 71 + 4
(x - 2)² = 75 ( take the square root of both sides )
x - 2 = ± 
= ± 5 ( add 2 to both sides )
x = 2 ± 5
then
x = 2 - 5 , x = 2 + 5
