1/2 x 5/8 = .3125
If you plug it into the calculator.
Answer:
9. 2a + 14
10. 7h - 70
Step-by-step explanation:
(2 x a ) + ( 2 x 7 )
(7 x h ) - ( 7 - 10 )
Answer:
Step-by-step explanation:
to find the "solution" to this system, set f=g.
then we get:
plugging in 3,-3 for x in both equations, we get:
(3,7),(-3,-7),(-3,-5)
There are no common factors between the two terms
13
x
and
10
- see explanation below.
Explanation:
First, we can try factoring the constants in each term:
13 is a prime number and therefore can only be factored to 1 and 13.
10 can be factored as (1 x 10) or (2 x 5).
Because there are no common factors other than
1
the constants cannot be factored.
And, because there is no
x
in the second term (10), we cannot factor an
x
out of the two terms.
Therefore this expression cannot be factored.
Answer:
81
Step-by-step explanation:
Given
x² - 18x = 29
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + (- 9)² = 29 + (- 9)²
x² + 2(- 9)x + 81 = 29 + 81
(x - 9)² = 110
