Since both terms are perfect squares, factor using the difference of squares formula,
a
2
−
b
2
=
(
a
+
b
)
(
a
−
b
)
where
a
=
x
4
and
b
=
16
.
(

Step-by-step explanation:
answer:
speed= 72 km - per • hour
Slope is change in y over the change in x.
Slope = (-7 - 2) / (-1 -2)
Slope = -9/-3
Slope = 3
20%.
20,000 times 0.8 is 16,000, so the decreased value that was lost was 20% of the original price.
Hello!
I'm assuming we're simplifying here
to simplify, use the distributive property of multiplication
2 * 3x = 6x
2 * (-5) = -10
6x - 10 is your simplified answer
I hope this helps, and have a nice day!
