Mathematics
1 answer:
laila [671]4 years ago
5 0

Answer:

Answers are below in bold.

Step-by-step explanation:

The first answer is correct. 1 m² = 10,000cm²

A=2(wl+hl+hw)        To find the surface area of the package, use this equation

A=2(18*50+20*50+20*18)      Multiply in the parentheses

A=2(900+1000+360)             Add in the parentheses

A=2(2260)                              Multiply

A=4520

The package has a surface area of 4520 cm²

The area of the package is less than the area of the wrapping paper.

So, Dayson can completely cover the package with the wrapping paper.

PLEASE HELP ASAP 25 POINTS
Elena L [17]

Answer: B

<u>Step-by-step explanation:</u>

 2x - 3y =  -7   →   2(2x - 3y = -7)   →   4x - 6y = -14

-4x + 6y = -10  →   1(-4x + 6y = -10) → <u>-4x + 6y</u> = <u>-10 </u>

                                                                    0  = -24

                                                                     FALSE

Since this makes a false statement, there are no solutions
