Hello from MrBillDoesMath!
Answer:
x = 0, +\-3
Discussion:
x^3 = 9x => subtract 9x from both sides
x^3 - 9x = 0 => factor x from both terms
x(x^2-9) = 0 => x = 0 or x^2 - 9 = 0
x = 0, +\-3
Thank you,
MrB
Answer:
11x + 1
Step-by-step explanation:
f(x) = 66x² + 17x + 1
Factoring:
f(x) = (6x + 1) (11x + 1)
Area of a rectangle is width times length. So if g(x) = 6x + 1, then h(x) = 11x + 1.
Answer:
I think it's a.)
Step-by-step explanation:
It says that they already started off with $400 and raise $80 a day, and <em>d</em> stands for the number of days.
It's basically $80 a day being added on to the $400 that was already collected.
So it's 80d+400=7,600
For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.
Therefore, we have the following equations:
From these equations, we can clear the values of the unknowns.
For equation 1 we have:
For equation 2 we have:
Answer:
The values of t and f are given by:
Answer:
y is 25.45
Step-by-step explanation:
y=1.65x+2.35 insert the unknown x
y=1.65(14)+2.35 open brackets by multiplication
y=23.1+2.35
y=25.45
