Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x + 10 = 0 ( subtract 10 from both sides )
x² - 8x = - 10
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 10 + 16
(x - 4)² = 6 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact solutions
2.6 is the aswer.
Why?take the 2 number after the decimal the estimate
Answer:
8y + 10
Step-by-step explanation:
3 + (7 + 8y) =
Apply the associative property:
= (3 + 7) + 8y
= 10 + 8y
Apply the commutative property:
= 8y + 10
She can read 55 pages per hour
So, divide that by 2 to get 27.5
She can read 27.5 pages in the next 30 Min.
(She would be on page 137.5 :p)
Hope this helps!!
