Answer:

12 square feet

Step-by-step explanation:

The shape of the top of the desk is a trapezoid.

Are the two figures congruent?
geniusboy [140]

Answer:

No, because the reflection of ABC is not congruent to A’B’C’.

Step-by-step explanation:

we know that

The rule of the reflection across the line y=x is equal to

(x,y) -------> (y,x)

so

A(-6,6) -------> A'(6,-6) ----> is ok

B(-3,3) ------> B'(3,-3) ----> is ok

C(-8,2) ------> C'(8,-2) ----> is not ok ( is not a reflection acros the line y=x)

therefore

The triangles are no t congruent, because the reflection of ABC is not congruent to A’B’C’

The equation y = 7x+25 gives the number of minutes it takes to prepare a meal y given the number of people being served x. Which
klemol [59]

<u>Answer-</u> C. For every extra person served, the time it takes to prepare a meal increases by 7  minutes.

<u>Solution- </u>

<em>y = 7x+25</em>

Where y = the number of minutes it takes to prepare a meal

           x = the number of people being served.

If the number of persons increased by one, so x' = (x+1)

Then y' = 7x' + 25 = 7(x+1) + 25 = 7x + 7 + 25 = 7x + 25 + 7 = y + 7

∴ As y gets increased by 7 for every 1 more person , so C is the correct answer.
