Step-by-step explanation:
The first one (f×g)(x) is asking you what is f of x times g of x. This means you multiply the function. You can multiply by the first term (5x) then the second (3) and combine like terms.


Combine like terms

The second one asks you to divide.
Factor out f(x):

From dividing f(x) /g(x)

To

Cancel like terms since (5x+3) is on top and bottom of fraction.
You get 3x+2
Hypotenuse, you can find it by using the <span>Pythagorean theorem</span>
Answer:
72 units
Step-by-step explanation:
A circle has a circumference of 452.16
The formula for circumference of circle = 
Where r is the radius of circle
The approximate value of pi = 3.14
Given circumference C= 452.16



Divide both sides by 6.28
r = 72
So radius of the circle 72 units
Answer:
<h2>700 (units

Step-by-step explanation:
Surface Area =2 length x width + 2 length x height + 2 height x weight
so we do:
7 x 12 = 84 84 x 2 = 168
7 x 14 = 98 98 x 2 = + 196
14 x 12 = 168 168 x 2= <u> + 336</u>
700
