Answer:
5 x^2 - 32
Step-by-step explanation:
Simplify the following:
3 x^2 + 2 x^2 - 32
Grouping like terms, 3 x^2 + 2 x^2 - 32 = (2 x^2 + 3 x^2) - 32:
(2 x^2 + 3 x^2) - 32
2 x^2 + 3 x^2 = 5 x^2:
Answer: 5 x^2 - 32
Answer:
35
Step-by-step explanation:
We are adding 8 and then subtracting 2
3, 11, 9, 17, 15, 23, 21
The 8th number is 21+8 = 29
The 9th number
Subtract 2
29-2 = 27
10th number
Add 8
27+8 = 35
Answer:
Step-by-step explanation:
The first line has a slope of -5/3 found using the points in the slope formula.
Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form 
.
The problem ask to compute or find the value of x if AC=12, BC = X+1, DC = 2X and EC = 9, base on the said data, and in my further calculation about the problem, i came u p with a solution that leads to an answer of X=2. I hope you are satisfied with my answer
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
