Answer:
A
Step-by-step explanation:
u = sqrt(x)
x = u²
dx/du = 2u
dx = 2u × du
x(x+2)²/sqrt(x) . dx
u² × (u²+2)]/u × 2udu
2 × u²(u²+2).du
Answer:
The answer is 4az + a + 4z − 4
Step-by-step explanation:
= a + 9az + - 4 + -5az + 4z
= a + 9az + -4 + -5az +4z
= (9az + -5az) + (a) + (4z) + (-4)
= 4az + a + 4z - 4
Answer:
20
Step-by-step explanation:
( x − 2 ) 2 − 16 Set y equal to the new right side. y = ( x − 2 ) 2 − 16 Use the vertex form, y = a ( x − h ) 2 + k , to determine the values of a , h , and k . a = 1 h = 2 k = − 16 Find the vertex ( h , k ) . ( 2 , − 16 )

Answer:
1/4x+27/4
Step-by-step explanation:
Here's the equation: -4y+x=-27
We'll need to isolate y on one side
subtract x from both sides
-4y=-x-27
divide everything by -4
y=1/4x+27/4
So you can substitute 1/4x+27/4 for y.
hope this helps!
