If f(x)= x^4 + 6,9(x)= x-8 and h(x) = sqrt of x then f(g(h(x)))=

Step-by-step explanation:

[i assume by 9(x) , you meant g(x)]

we start from the inner one, h(x):

now to the g(h(x):

now to the f:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
