-78
Step-by-step explanation:
(7-8)(78)
(-1)(78)=-78
a^ - b^ a squared minus b squared.
use distributive property of multiplication. FOIL (first, outside, inside, last)
a *a = a^ - b*a= ab (or ba) + b*a = ba (or ab) - b*b= b^
a squared - ab +ab - b squared
Negative ab and positive ab = 0 therefore you are left with
a^ - b^
Answer:
(-36 x^3)/25
Step-by-step explanation:
Simplify the following:
(-4×9 x^2 x)/(5×5)
Combine powers. (9 x (-4) x^2)/(5×5) = (9 x^(2 + 1) 4 (-1))/(5×5):
-(9×4 x^(2 + 1))/(5×5)
2 + 1 = 3:
((-9×4 x^3)/5)/5
9 (-4) = -36:
(-36 x^3)/(5×5)
5×5 = 25:
Answer: (-36 x^3)/25
9.235
"nine and two hundred thirty-five"
You're going to start with the number(s) before and which would be 9 in this case then lake your number(s) after the and, the number would be 235 in this case now you have 9 and 235 replace the and for a decimal and you will get your answer :) 9.235
