The equivalent expression is 12x+30y and the area is 156 ft².

Using the distributive property, we have
6(2x+5y)
6*2x+6*5y
12x+30y

If x=3 and y=4,
12*3+30*4
36+120
156

If f ( x ) = x^4 + 4 , g ( x ) = x − 6 , h ( x ) = √ x , then f ∘ g ∘ h ( x ) =

yanalaym [24]

Answer:

$f(g(h(x))) = (\sqrt{x} -6)^4 +4$

Step-by-step explanation:

Given:

$f(x) = x^4 +4$

$g(x) = x -6$

$h(x) = \sqrt{x}$

Solution:

$f°g°h(x) = f(g(h(x)))$

We can solve for $g(h(x))$ to make it less complicated.

$g(h(x)) = h(x) -6 \\ g(h(x)) = \sqrt{x} -6$

Now we can solve for $f(g(h(x)))$ .

$f(g(h(x))) = g(h(x))^4 +4 \\ f(g(h(x))) = (\sqrt{x} -6)^4 +4$

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. Th

Feliz [49]

Answer:

28%

Step-by-step explanation:

We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.

First, subtract the two numbers

94 - 68 = 26

Put 26 over 94 to make this 26/94

Divide to get 0.28 (simplified and rounded)

So the increase was 28%
