HELP! (WILL MARK BRAINLIEST!)

Mathematics
1 answer:
givi [52]3 years ago
4 0

Step-by-step explanation:

<u>Step 1:  Identify the blanks</u>

<u />f(x) = \sqrt{x-3} and g(x) = 2x + 4

f · g = f( g( x ) )

      = f( 2x + 4 )

      = \sqrt{(2x + 4) - 3}

      = \sqrt{2x + 1}

Since the g(x) is in the inside, that is what goes in first to produce the f(2x + 4).  Now we put in (2x + 4) into the x of the f(x) function.  

<u>This produces:</u>  \sqrt{(2x + 4) - 3}  

<u>Now, we just combine like terms to get:</u>  \sqrt{2x + 1}

Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. M
jolli1 [7]

Answer:

i. No, Maurice statement is wrong.

ii. Stephan does not have sufficient pieces of wood to make the tray because the square inches required is more than what he has.

Step-by-step explanation:

Stephan's piece of wood measures; 18 inches in length and 12 inches in width.

Since the piece of wood has a shape of a rectangle,

the area of the piece of wood = length × width

                                                = 18 × 12

                                               = 216 square inches

According to Maurice's statement, he could make a tray that has a base of 1012 inches by 1012 inches.

The base has the shape of a square, so that;

    the area of the base = length × width =

                                      = 1012 ×1012

                                     = 1024144 squared inches

This shows that Stephan does not have sufficient wood to make the tray because the square inches required is more than what he has. and 16 more users found this answer helpful
