Hayley has x pieces of candy, hayden has 3 more than hayley, and you have twice as many as hayden. if you have 38 pieces of candy, how many does hayley have ?

The number of candies Hayley  has is  16 .

Step-by-step explanation:

The number of candies Hayley has = x

So, Number of candies Hayden has = (x + 3)

Then the Number of candies i have = 2(x + 3)

Also,according to the question:

2(x + 3) = 38

or, 2x + 6 = 38 ⇒    2x = 32

or, x = 32/2 = 16

⇒  x = 16

So, the number of candies Hayley  has is  x = 16 .

the answer is (2x+8)²= 16

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
