<u>C. 42 units</u>
Step-by-step explanation:
I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.
To do this, you will multiply the length of AE by 2 and set it equal to BD.
Then distribute, multiply what is in the parentheses by 2.
Subtract 4x from both sides.
Subtract 2 from both sides.
x = 8
Now that we have x, we can plug it into the equation to find BD.
BD is equal to 42 units, so we know...
<u><em>AC = 42 units</em></u>
This is what I got I hope it can help you
Answer:
Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,
where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:
simplify addition:
simplify division:
simplify multiplication:
since we multiply two same units we of course have to use square unit
hence,
Answer:
16m
Step-by-step explanation:
solve it out: 16*(9+3)
Answer:
g(- 2) = 11
Step-by-step explanation:
To evaluate g(- 2) substitute x = - 2 into g(x) , that is
g(- 2) = 3(- 2)² - 1 = 3(4) - 1 = 12 - 1 = 11
