Answer:
14
Step-by-step explanation:
you can simplify it by turning a²+b²/a-b
into
(a-b)²+2ab / a-b
eliminate the fraction
a-b +2ab
a=-1
b=-5
-1-(-5)+2*-1*-5
-1+5+10 = 14

Answer:
240 miles
Step-by-step explanation:
To solve this we need to write an equation. For this problem let <u>d be the distance traveled</u>. We know that the new train (being much more modern than poor old Thomas who is long retired) can go 20% further. To show this we will take 20% of 200 and then add that to the original distance.
Our equation would look something like this:
d=200+(20%·200)
[one more little note: to find percentage take your percent and convert it into a decimal 20%=0.2)
d=200+(0.2·200)
d=200+40
<u>d=240</u>
Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
C. 3w + 8 - w = 4w - 2(w - 4)
(3w - w) + 8 = 4w - 2w -2(-4)
2w + 8 = 2w + 8
