Answer:
1.5^2 = 2.25
(it looks like 1.5 but if it's 15 then it would be 225)
Step-by-step explanation:
1.5^2 means (1.5*1.5) you multiply the number by itself by how many it says to do. So if it were 1.5^52 you would multiply 1.5 by 1.5, 52 times.
I cant draw to show it on the number line
Answer:
c = 49/4
Step-by-step explanation:
The given expression is x^2 - 7x + c
This trinomial must be a perfect square.
Therefore, c must be a prefect square number.
So b^2 - 4ac = 0. That is discriminant must be equal to zero.
In the given expression a =1 and b = -7
Now plug in these values in the discriminant formula.
(-7)^2 - 4*1*c = 0
49 -4c = 0
4c = 49
c = 49/4
x^2 - 7x + 49/4 = (x - 7/2)^2
which is perfect square trinomial.
Thank you.
Answer: 24 goals
Step-by-step explanation:
Melissa makes 2 goals out of every 12 shots on goal.
This means that the amount of shots needed to score a goal for her is:
= Number of shots / Number of goals
= 12 / 2
= 6 shots
She scores a goal every 6 shots.
If she makes 144 shots therefore, she will score:
= Number of shots / Number of shots needed per goal
= 144 / 6
= 24 goals
Answer:
9x + 8.
Step-by-step explanation:
2(x - 3) + 7(x + 2)
= 2x - 6 + 7x + 14
= 2x + 7x - 6 + 14
= 9x + 8.
Hope this helps!
