Answer: 
This is the same as
and it is also equivalent to 
=====================================================
Explanation:
n is some placeholder for a number
one fourth of that number is
which is the same as
or
since 1/4 = 0.25
From here, we subtract off 2 to get
as one possible final answer.
The two parallel bases b1 and b2 are
b1 = 12
b2 = 9
the order of which base you pick doesn't matter
The height is h = 10 and it's perpendicular to each base.
The area is...
A = (1/2)*h*(b1+b2)
A = (1/2)*10*(12+9)
A = (1/2)*10*(21)
A = 5*21
A = 105
Final Answer: B) 105 square centimeters
Answer:
28%
Step-by-step explanation:
you can divide 276 by 100 to get how much each individual percentage is worth so when you multiply that number by 28 you get 77.28
The answer would be: -5
Heres how you solve it!
First, change the x into a 0 so it can be removed.
y+2= -3/4*4
Now with the GCF you can reduce the numbers with 4.
y+2= -3
Then move the 2 to the other side causing it to change its sign into a negative
y= -3-2
Since -3 and -2 are both negative it would be -5
y= -5
then you are left with your answer.
Hope this helps! :3
