Answer:
=−5.75x−17.4
Step-by-step explanation:
=−0.25x−8+−1(5.5x+9.4)
=−0.25x+−8+−1(5.5x)+(−1)(9.4)
=−0.25x+−8+−5.5x+−9.4
another way >>>><<<<
=−0.25x+−8+−5.5x+−9.4
=(−0.25x+−5.5x)+(−8+−9.4)
=−5.75x+−17.4
Answer:
=−5.75x−17.4
Answer:
49 - x^2
Step-by-step explanation:
(7+x)(7-x)
We know this is the difference of squares
(a-b) (a+b) = a^2 - b^2
7^2 - x^2 = 49-x^2
We can also FOIL
first = 7*7 = 49
Outer: = 7x
Inner: = -7x
Last : -x*x = -x^2
Add them together
49 +7x-7x - x^2
Combine like terms
49-x^2
80*.65=52
15%(80)=12
