Answer:
x=8cm
Step-by-step explanation:
32=4x
divide both sides by four to get 8=x
32/4=8
4x/4=x
8=x
First question
Volume = height * radius*radius*3.14
5*3*3*3.14 = 141.3 in3
Second qustion
Violume = height * radius * radius * 3.14
28*8*8*3.14= 5626.88 cm3
So the answer is 1875.63 because it's the closest
Answer:
x=4 y=8
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation
Answer: fg(x) = 16x² + 32x
Method:
First you must substitute g(x) into f(x).
Where the x is in the equation f(x) substitute the equation of g(x).
So it should be fg(x) = (x4)²+ 8(x4).
Then simplify the equation to
fg(x) = 16x² + 32x
The answer would be is 0.5
