If she wants to frame a square painting with an area of 400 square inches, all you would have to do is to find the square root of 400, which is 20. Thus, each side is 20 inches long.
If you have to set an equation up, it would simply be:
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120

Answer:
2
Step-by-step explanation:
A factor is a number that can evenly divide into another number.
Let’s list all the factors of both numbers.
26: 1, 2, 13, 26
14: 1,2, 7, 14
Now find the GCF, or greatest common factor. The biggest number that is a factor of both 26 and 14 is 2.
Therefore, the GCF of 26 and 14 is 2.
Answer:
14th term of geometric sequence 7, 28, 112 is 469762048
Step-by-step explanation:
Geometric sequence : 7, 28, 112, .....
First term = a = 7
Common ratio = r =
Common ratio = r =
Formula of nth term =
Substitute n = 14
So,
Hence the 14th term of geometric sequence 7, 28, 112 is 469762048
