Expand the brackets by multiplying everything in the brackets by 4
4x+4-2x
simplify
2x+4
You could set up a ratio:
which then becomes:
Answer: the answer is 100
Step-by-step explanation:
100*100=10,000
10,000/100=100
11m
The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
I belive the answer to your question would be -7a^2b^3
