Answer:
John = 41 years
Sam = 32 years
Step-by-step explanation:
For the first one Y = -6
3x + 2Y = -16
-2y -2y
3x = -18y
— —
3x 3x
Then divide -18y divided by 3X
To get Y= -6
Hope that helped!
Answer:
The volume formula is:
Volume = (4/3) * PI * radius ^ 3
Volume = (4/3) * PI * 7.5 ^3
Volume = 1,767.1458676443
Volume = 1,767 cubic centimeters
Step-by-step explanation:
f(x) = 3x²
g(x) = 4x³ + 1
f(g(x)) = 3.(4x³ + 1)²
As we know
(a + b)² = a² + 2.a.b + b²
So,
(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² = ![4x^6+8x^3+1](https://tex.z-dn.net/?f=4x%5E6%2B8x%5E3%2B1)
f(g(x)) = 3.(
)
The degree is the maximum exponent, so, 6.
