Answer:
Step-by-step explanation:
hg(x) means you multiply h(x) times g(x) and then we will set it equal to 
.
hg(x) = 
which simplifies to
. Now set that equal to :
and get everything on the same side and factor:
. Factor by grouping:
and factor out what's common in each set of ( ):
which factors out to
. But 
factors somoe to:
(x + 1)(x - 1)(x - 1) = 0 So the solutions for this are
x = -1, 1
-2x cube + 2x cube makes 0, so u can delete it,
then 6x + 10x makes 16x,
so the final answer should be 16x+7xtothepower4
Answer:
7.5% error
Step-by-step explanation:
Percent Error = ( | measured - real | / real ) x 100%
|430 - 400| / 400 = |-30| / 400
( 30 / 400 ) x 100%
= 7.5%
Answer:
16, 74
Step-by-step explanation:
3x +10 + 12x +50 = 90
15x + 60 = 90
15x = 90 -60
15x = 30
x = 30/15
x = 2
3x + 10 = 3*2 +10 = 6 +10 = 16
12x + 50 = 12*2 +50 = 24 + 50 = 74
2.45 pounds is more because that equals to a little over .40% more than 1/16 as a fraction which would be more over to the right making it a smaller digit
