$120 and the ratio is 3:2
$200 6:4 and half
Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt( x+9)
g(x) = 8x-13
f(g(x))
place the function g(x) in for x in f(x)
f(g(x)) = sqrt(8x-13+9)
Combine like terms
f(g(x)) = sqrt(8x-4)
Factor out 4
f(g(x)) = sqrt(4*(2x-1)
2 sqrt(2x-1)
Answer:
A=4.
Step-by-step explanation:
Note: In the expression of area the first term should be
.
It is given that area of a rectangular floor of your house is
and the length is
units.
We know that, area of a rectangle is
Since length of the rectangle is
, therefore
is a factor of
and the value of
is 0 at x=-2.
Divide both sides by 4.
Therefore, the value of A is 4.
