Answer:
<em>x² - 28x√x + 294x - 1372√x + 2404 </em>
Step-by-step explanation:
f(x) =
+ 3
g(x) = x - 7
h(x) = √x
f(g(h(x))) - ?
g(h(x)) = √x - 7
f(g(h(x))) =
+ 3 = ( √x - 7 )² × ( √x - 7 )² + 3 =
= (x - 14√x + 49)(x - 14√x + 49) + 3 =
= x² - 14x√x + 49x - 14x√x + 196x - 686√x + 49x - 686√x + 2401 + 3 =
= <em>x² - 28x√x + 294x - 1372√x + 2404</em>
The property used in the equation is called Distributive property.
<h3>What is
Distributive property?</h3>
The distributive Property States that when a factor is multiplied by the sum/addition of two terms, it is essential to multiply each of the two numbers by the factor, and finally perform the addition operation.
Given an equation, 4 x (5 + 6) = (4 x 5) + (4 x 6)
The property used in this equation is distributive property.
a(b+c) = (a*b)+(a*c)
Hence, The property used in the equation is called Distributive property.

First, we need to find his unit rate, the amount he earns in 1 hour.
So, we have to divide 28.50 by 2.
That is:
28.50 / 2 = $14.25 per hour
To find the amount he earns in 8 hours, we will need to multiply hourly rate found by "8". So,
14.25 * 8 = $114
<h2>Rolando earns $114 in 8 hours</h2>
0.45 * 2 is 0.9
$1.44 * 2 is $2.88
$1.44/9 is $0.16
$0.16 * 2 is $0.32
$2.88+$0.32 is $3.20
The answer is $3.20
Answer:
B) 6.5 inches by 3.5 inches
Step-by-step explanation:
Multiplying the actual dimensions by the scale gives the scale dimensions:
(0.5 in)/(6 ft) × {78 ft, 42 ft}
= {39/6 in, 21/6 in}
= {6.5 in, 3.5 in}
The size on the scale drawing is 6.5 inches by 3.5 inches.
