Answer:
f(x + 1) = 2x² + 4x + 5
Step-by-step explanation:
Step 1: Plug in (x + 1) in as <em>x</em> in f(x)
f(x + 1) = 2(x + 1)² + 3
Step 2: Expand and distribute
f(x + 1) = 2(x² + 2x + 1) + 3
f(x + 1) = 2x² + 4x + 2 + 3
f(x + 1) = 2x² + 4x + 5
Answer:
x=9 :))
Step-by-step explanation:
First set up your equation.
"3 times" is multiplication
"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it
"is increased by ten" that is an addition at the end
Now we have 3(x+7)+10=4
Solve your equation!
Distribute the 3 now we have 3x+21+10=4
Add like terms
now it should look like this... 3x+31=4
Subtract 31 from both sides and it looks like...
3x=27
Divide by the x-value
x=9
3x+2=4x^2 would turn into -4x^(2)+3x+2=0 If you want X you would need to use x=3+- sqrt (41) divided by 8.
There you go hoped I helped. :)
Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
