We are told that f(x) = x + 2. We want to find .
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
Y equals thirty two divided by two to the x power
y=32/(2^x)
I don't know how to put this into the form you needed, because I don't think that is possible, but perhaps the first blank is 32 the second is 1 and the third is 2 to the power of x

Answer:
Rs 400
Step-by-step explanation:
The selling price was ...
cp(1 -10%)
where cp is the cost price. If we add Rs 60 to that, then the selling price would be ...
cp(1 -10%) +60 = cp(1 +5%)
60 = 15%·cp . . . . . . . . . . . . . . . subtract 90%·cp
60/0.15 = cp = 400
The cost of the shirt was Rs 400.
Answer:
They are not similar because Segment BR to segment DB is 1:2 and Segment KE to segment YK is 1:3.
Step-by-step explanation:
If you draw the kites, you see they have different aspect ratios. The width to length ratio of KELY is greater than for ADBR. So, only the "not similar" answer choices are viable, and the only one of those that makes sense is the one that says ADBR is shorter/fatter than KELY.
