Nookie1986 [14]

Answer: A=2.5x^{2}


Step-by-step explanation:

1. Let's write the following formula for calculate the area of a rectangle:

A=yx

Where y is the lenght (the longer side) and x is the width (the shorter side).

2. You know that the length is 2.5 times as long as the other side, which indicates a multiplication. Then:

y=2.5x

3. So, you must substitute y into the equation for calculate the area of the rectangle and then you must simplify.

4. Then, you obtain the following expression:

A=(2.5x)(x)\\A=2.5x^{2}

aniked [119]

Answer:

2h 1' 1"

Step-by-step explanation:

1h = 1 hora

1' = 1 minute

1" = 1 secind

The sum of the three days is:

  58'  45"

+ 40'  40"

  20'  36"

= 118'  121"

118' 121" = 118' + 121"

1' = 60"

121" = 120" + 1"  = (120/60) + 1 = 2' + 1"

Then:

118' + 121" = 118' + 2' ´+ 1" = 120' + 1"

1 h = 60'

(120/60) + 1 = 2h + 1'

then:

118' + 121" = 2h + 1' + 1"

= 2h 1' 1"
