First rewrite the mixed number as an improper fraction:
-1 1/14 = -15/14
Now you have :
-3/7 / -15/14
When dividing by a fraction, flip the second fraction over and change divide to multiply:
-3/7 x -14/15
Now multiply top by top and bottom by bottom:
(-3 x -14) / ( 7 x 15) = 42/105
Simplify by diving each number by 21 to get the final answer :
2/5
Answer:
80
Step-by-step explanation:
area of trapezoid is given by formula
Area = 
h
where a is one base, b is another base and h is height
In given case, we have
a= 7+7+3 = 17
b= 3
h= 8
Substituting the values
Area= 
x 8
= 
x 8
= 10 x 8
= 80
!
The answer for that would be 20.75
Answer:
b
Step-by-step explanation:
Distribute parenthesis and collect like terms, noting that the second parenthesis is distributed by - 1
(4x² - 8xy +2y²) - (9x² - 4xy - 7y²)
= 4x² - 8xy + 2y² - 9x² + 4xy + 7y² ← collect like terms
= (4x² - 9x²) + (- 8xy + 4xy) + (2y² + 7y²)
= - 5x² - 4xy + 9y² → b
