Answer:

(g + h)(a) = 9

Step-by-step explanation:

g(a)= 4a +4

h(a)= -4a + 5

(g + h)(a)

We add the functions

(g + h)(a) =  4a +4 + -4a + 5

Combine like terms

(g + h)(a) =0a +9

The scale of a model train is 1 inch to 13.5 ft. One of the cars of the model train is 5inches long. What is the length in feet
aleksklad [387]

Answer:

The length of the actual train's car is <u>67.5 feet.</u>

Step-by-step explanation:

Given:

The scale of a model train is 1 inch to 13.5 ft.

Now, to get the length of the actual car of the train.

Let the length of actual train's car be x.

And, the length of the car of model train = 5\ inches\ long.

<em>According to the scale of the model train, 1 inch is equivalent to 13.5 ft. </em>

<em>Thus, 5 inches is equivalent to </em>x.<em />

Now, to get the length of actual train's car using cross multiplication method:

\frac{1}{13.5} =\frac{5}{x}

By cross multiplying we get:

x=67.5\ feet.

Therefore, the length of the actual train's car is 67.5 feet.

Can someone help me with this f(g(x))=2(3x-4)^2+5?
Greeley [361]

Answer:

f(x)=349525

Step-by-step explanation:

f(x)=2(3x-4)^2+5

f(x)= 6x - 8^7

f(x)= 6x - 2,097,152

f(-6x)= - 2,097,152

/-6x       /-6x

f(x)=349525


I hope I am not terribly wrong but I probably am good luck

What is the greatest value of 2,463.9051
RoseWind [281]

Hey There @Bre18016,

The answer is \boxed{2}

The greatest value of 2,463.9051 would be the thousands place (2) simply as it is the biggest number out of the other places.

For instance, if we had the number 300, 3 would be the greatest value.

Or let's say we had 10,000 the 1 would be the greatest value.

Furthermore, you could look at the first digit in the entire number to deter mine the greatest value.
