Answer:

- 3(5n - 8) =  - 8(n - 3)

- 15n + 24 =  -8 n + 24

- 15n + 8n = 24 - 24

A rectangular room is 7 times as long as it's wide and it's perimeter is 64metres. Find the dimension of the room.
wlad13 [49]

Answer:

  • Length = 28 meters
  • Width = 4 meters

Step-by-step explanation:

Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.

Perimeter of a rectangle:

= Length + length  + Width + Width

Therefore:

7x + 7x + x + x = 64

16x = 64

x = 64/16

x = 4 meters

Length is 7 times as long:

= 4 * 7

= 28 meters

zimovet [89]

Answer:

6.32 feets

Step-by-step explanation:

Given that:

Height of ramp = 2 feets

Length of base = 6 feets

Length of ramp = l

Using Pythagoras rule :

Hypotenus = sqrt(opposite² + adjacent²)

Length of ramp = sqrt(height of ramp² + length of base²)

l = sqrt(2² + 6²)

l = sqrt(4 + 36)

l = sqrt(40)

l = 6.3245

Length of ramp = 6.32 feets

Rearrange like terms in this polynomial so like terms are next to each other
mixer [17]

Answer:

4x^2 - 6x^2   -6x + 3x    +3 - 4

Step-by-step explanation:

The terms here involve x^0, x, x^2.

Write the x^2 terms first:  4x^2 - 6x^2;

then write the x terms:  -6x + 3x; and

then write the constants:  3 - 4

and so we have, in descending powers of x,

4x^2 - 6x^2   -6x + 3x    +3 - 4
