  • \sf{length=28~ft }
  • \sf{width=7~ft}

Step-by-step explanation:

The length of a rectangle is four times its width.

If the perimeter of the rectangle is 70 ft,

let the width =x

length =4width=4x

<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>

the perimeter of the rectangle is 70 ft

  • 2(length+width)=perimeter
  • 2(4x+x)=70
  • 2(5x)=70
  • 10x=70
  • x=70/10
  • x=7

<u>Therefore</u><u>:</u><u>-</u>

width =x=7ft

length =4x=4×7=28ft

Let width be x

  • length=4x

ATQ

\\ \sf\longmapsto 2(x+4x)=70

\\ \sf\longmapsto 5x=35

\\ \sf\longmapsto x=7

  • Width=7ft
  • Length=7(4)=28ft

Write the expression: the quotient of the quantity k minus 12 and m. A) 12 − m k B) m − 12 k C) 12 − k m D) k − 12 m
Len [333]

Answer:

Option D) (k − 12)/m                          

Step-by-step explanation:

We have to write an expression:

the quotient of the quantity k minus 12 and m.

k minus 12 can be written as:

k - 12

The quotient of (k-12) and m means (k-12) is divided by m.

This can be written as:

\dfrac{k-12}{m}

Thus, the correct answer is

Option D) (k − 12)/m

Help please i dont know this thank you&lt;33
jok3333 [9.3K]

Answer:

  • 42
  • 35
  • 16

Step-by-step explanation:

Put the value where the variable is and do the arithmetic. It can save some steps to simplify the expression first.

  35 -c³ +8 = 43 -c³

<u>c = 1</u>

  43 - 1³ = 43 -1 = 42

<u>c = 2</u>

  43 - 2³ = 43 -8 = 35

<u>c = 3</u>

  43 -3³ = 43 -27 = 16

The values that go in the blanks are 42, 35, 16.

<em>Additional comment</em>

It does not take long to learn how to use a spreadsheet for evaluating the same formula with a number of different values of the variable(s). Graphing calculators can do this, too. It is always appropriate to use the right tool for the job.

Familiarity with multiplication and addition facts is a very good place to start. It is also useful to memorize the squares and cubes of small integers. The latter are needed here.
