Answer:
subtraction
Step-by-step explanation:
x +15 = 9
-15 = -15
x = -6
Answer:
18.8 miles.
Step-by-step explanation:
(b)(h)/2 = A.
In this circumstance, you are solving for h.
Isolate h.
h = 2 x A/b
Now, substitute 102.46 for A and 10.9 for b.
h = 2 x 102.46/10.9 = 2 x 9.4 = 18.8.
h = 18.8mi.

Step-by-step explanation:
f(h(x))= 2x -21
Step-by-step explanation:
f(x)= x^3 - 6
h(x)=\sqrt[3]{2x-15}
WE need to find f(h(x)), use composition of functions
Plug in h(x)
f(h(x))=f(\sqrt[3]{2x-15})
Now we plug in f(x) in f(x)
f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6
cube and cube root will get cancelled
f(h(x))= 2x-15 -6= 2 x-21
wait i think i did the wrong one brb
30%
percent means parts out of 100 so 30%=30/100=3/10
42 is 3/10 of x
'of' can be translated to multiply
42=3/10 times x
multiply both sides by 10/3 to get rid of fraction
420/3=x
140=x
the number is 140
