Answer:
Length of the base is 21.34 inches.
Step-by-step explanation:
Area of parallelogram(A) is given by:
where b is the length of the base and h is the height of the parallelogram respectively.
As per the statement:
A parallelogram with an area of 160.5 in^2 has a height that measures 7.5 in.
Area of a parallelogram(A) = 160.5 square inches.
height of a parallelogram(h) = 7.5 in.
Then by formula of area of parallelogram we have;
Divide both sides by 7.5 we get;
21.34 = b
Therefore, the length of the base is 21.34 inches.
10(4x+3)-9x
40x+30-9x
31x+30
I think the answer is A
We factor the denominators
Factor x^2 - 16
x^2 - 4^2
We use a^2 - b^2 = (a+b)(a-b)
so x^2 - 4^2 = (x+4)(x-4)
Replace it in the given equation
Excluded values are the values that makes the denominator 0
we have (x-4) and (x+4) in the denominator
We set the denominator =0 and solve for x
x-4 =0
Add 4 on both sides
x= 4
x+4=0
subtract 4 onboth side
so x= -4
Excluded values are x=-4 and x=4
Multiply by 80 and you will get how many boys play video games daily.
44 is the number of boys who play video games daily.
Answer:
add 7 to both sides
then you are left with 5f=30
divide by 5 on both sides
you get f=6
