Answer:
4b² - 16
Step-by-step explanation:
The formula to find the area of a parallelogram equals
, where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.
Therefore, the answer is 4b² - 16.
Answer:age of the man: 75 age of the woman:25
Step-by-step explanation:
First, We need to define the variables
x: age of the man
y: age of the woman
at the first time he has three times her age
x=3y (1)
in 25 years time
(x+25)=2(y+25) (2)
we clear the equation
X+25=2y+50
X=2y+25
we substitute in the (1) equation:
2y+25=3y
y=25
x=3*25=75
C. Divide the numerator by the denominator.
Answer:
21
Step-by-step explanation:
A=1/2bh
252=1/2(24)(h)
multiply 1/2 and 24
252=12(h)
divide ( 252/12 12/12)
h=21
