I hope this helps you
A=(a+b).h/2
2A=(a+b).h
2A/h=a+b
a=2A/h-b
a=2A-b.h/h
3.75-3.44=0.31 change=0.31 3.44 is original, percent change=change/original percent change=0.31/3.44=0.0901162...=9% change answer is 9%
Answer: C, the answer would be 8
Explanation: simplify by breaking the radican up into a product of known factors, which would leave you with 8
Hope this helps!
I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
Answer:
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
We must find the slope using the slope formula.
Slope:
We substitute and
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is .
We will substitute and .
This is the equation of the line perpendicular to the equation line through the points given that crosses through (14,8).
