Answer:
C) 100 m^2
Step-by-step explanation:
Area of a trapezoid= h*[(b1+b2)/2]
h=10
b1=8
b2=12
Therefore:
A=10*[(8+12)/2]
A=10*(20/2)
A=10*10
A=100
So the area of the trapezoid is 100 m^2
Perimeter is the sum of all the sides. So we can set up an equation:

Now solve for 'x', combine like terms:
When it comes to terms with variables it's just like normal addition but we keep the variable:


So we have:

Add:

Subtract 7x to both sides:

Subtract 4 to both sides:

Divide 5 to both sides:
Answer:
-73
Step-by-step explanation:
substitue the -8 in for x. then multiply -8 by 7 you get -56. then subtract 17.

Step-by-step explanation:
Answer:
1/6, 2/3, 15/18
Step-by-step explanation:
get a common denominator
2/3 times 6
15/18 times 1
1/6 times 3
new fractions : 12/18, 15/18, 3/18
so it would be 3/18, 12/18, 15/18
then just revert it back to the original fraction and you have your answer
