The answer is 2. You can find it by multiplying 20 and 21 giving you 420 and since 420 is half of 840 then all you would have to do is multiply 420 by 2 meaning the height is 2 since if you multiplied all in one it would be 20 x 21 x 2=840
Answer:

Step-by-step explanation:
Given that:
f(x) approaches 150, and
g(x) approaches 0, with g(x) < 0,
as x approaches 3.
This means:

We need to evaluate:

Distributing the limit to numerator and denominator, we get:

The expression will result in infinity as the answer, but since, g(x) < 0, this means g(x) is approaching 0 from the negative side. As a result, the expression 150/0 will approach negative infinity as x will approach 3.
Therefore, we can conclude:

Answer:
45
Step-by-step explanation:
Set up ratios for 2 similar triangles:
20/28=x/x+18
Cross multiply
28x=20x+360
8x=360
x=45
Answer:
Step-by-step explanation:
soda pop
Step-by-step explanation:
To start, every term has an
x
in common, so we can factor that out. Doing this, we get
x
(
x
2
+
x
−
42
)
=
0
What I have in blue can be factored by a thought experiment. What two numbers have a sum of
1
and a product of
−
42
?
After some trial and error, we arrive at
−
6
and
7
. Thus, this business can be factored as
x
(
x
−
6
)
(
x
+
7
)
=
0
We can leverage the zero product property here, setting all three terms equal to zero. As our zeroes, we get
x
=
0
,
x
=
6
, and
x
=
−
