Answer: the system of equations are
3x + y = 14
y = 4x
Step-by-step explanation:
Let x represent the number of three point shots that Hailey made.
Let y represent the number of free throws(worth one point each) that Hailey made.
Hailey made some three point shots and some free throws and
scored a total of 14 points. This would be expressed as
3x + y = 14
Hailey made 4 times as many free throws as three point shots. This would be expressed as
y = 4x
Answer:
A
Step-by-step explanation:
We need to find the volume of the pyramid. The volume of a square pyramid is denoted by: , where B is the base area and h is the height.
Here, we know that the height of the pyramid is 12 and that the square base has dimensions 10 by 10. That means the base area is just 10 * 10 and the height is h = 12.
Plug these into the equation:
Thus, the answer is A.
Hope this helps!

Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
Answer:
Step-by-step explanation:
The answer is 4.
Once you add 4, you get:
x^2 -2x + 4 = 7.
The left side is factorable:
(x-2)^2 = 7.
There is your perfect square.
