Answer:
905
Step-by-step explanation:
So your original equation is f(x) = x² + 5
First lets work with the stuff inside the parentheses.
f(5) = 5² + 5 = 30
So now you are finding,
f(f(5)) => f(30)
f(30) = 30² + 5 = 900 + 5 = 905
Answer:
0.6
Step-by-step explanation:
First make them into decimals so.
9.4 - 8.8 = 0.6
<h3><u>d^3 - 4bd^2 + 16b^2d - 64d^3 is the expanded binomial.</u></h3>
The binomial theorem involves Pascal's triangle, and essentially gives you the coefficients for the formula you're going to use to expand it.
In this case, the coefficients will be 1, 3, 3, and 1.
We can set up our formula like this:
(a + (-b)) = a^3 + a^2b + ab^2 + b^3
Now we can just plug in our values:
(d + (-4b))^3 = d^3 + d^2(-4b) + d(-4b)^2 + (-4b)^3
Now, we can simplify the equation.
(d + (-4b))^3 = d^3 - 4bd^2 + 16b^2d - 64d^3
Answer: x = 2y
Step-by-step explanation:
Let's solve for x.
2(3x+4y)=4x+12y
Step 1: Add -4x to both sides.
6x+8y+−4x=4x+12y+−4x
2x+8y=12y
Step 2: Add -8y to both sides.
2x+8y+−8y=12y+−8y
2x=4y
Step 3: Divide both sides by 2.
<u>2x
</u>
2
=
<u>4y
</u>
2
x=2y
Answer:
x=2y
