Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
Answer:
Parallel means they have the same slope so, y=3x-8
Answer:
The height is 8.3 feet
Step-by-step explanation:
The area of a trapezoid is calculated using the formula:
Area=½(sum of bases)*height
We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.





An equation says that two things are equal. It will have an equals sign (assuming you know what that is) like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right.
Basically, it's a statement saying "equals that"
I don't fully understand your question, but I hope it helped you at least a little.
