25x/45=-65
25x=2925
x=117
I wasn't sure if you wanted a solution
You would expand becausee it isn't equal to anything
(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one
so
for the 3rd power

a=x
b=3

=
Answer:
At least 98 is needed in the 5th game
Step-by-step explanation:
The missing parameters are:




at least
Required
The score in game 5 to make you advance
Mean is calculated as:

So, we have:


The mean must be at least 90.
So, we have:

Multiply both sides by 5


Make Game 5 the subject


<em>At least 98 is needed in the 5th game</em>
Answer:
y-inctercept=4, x-intecept=7
Step-by-step explanation:
I did it with the standard to slope again!


Now don't get confused here, 4 is the y incetecept, not -4.
When y=0, x=7
UPDATE:
To determine x and y intercept using graph, see where the line intersects at the x or y axis.
The answer to this question is B.
