PLEASE HELP MEEEEEEEEEEEEEEEEEE

DerKrebs [107]

Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

<u>Given</u>:

<em>Dimension of the living room:</em>

<em /> $l = 4.9 $ m\\w = 6 $ m$

<em>A. </em><em>Perimeter </em><em>of the carpet = perimeter of a </em><em>rectangle</em>

Perimeter = $2(l + w)$

Substitute

$Perimeter = 2(4.9 + 6)\\= 21.8 $ m$

Perimeter of the carpet = 21.8 m (The digits here are significant)

<em>B. </em><em>Area </em><em>of the carper = </em><em>area </em><em>of a </em><em>rectangle </em>

Area = $l \times w$

Substitute

$Area = 4.9 \times 6\\= 29.4 $ m^{2}$

Area of the carpet = $29.4 $ m^{2}$ (the digits here are significant)

Therefore, considering the rules of significant digits:

Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

The sum of three consecutive odd integers is − 87 . find the numbers.

DIA [1.3K]

Three consecutive odd integers are n, n+2 and n+4

n + n+2 + n+4 = -87
3n + 6 = -87
3n = -87 - 6
3n = -93
n = -93/3
n = -31

n+2 = -31 + 2 = -29
n+4 = -31 + 4 = -27

The numbers are -31, -29 and -27

gizmo_the_mogwai [7]

Well it should be like this tell me if im wrong, ↓

3D + 12
___ ___

3 3

so, hypo thinking once 3 is divided should leave you with . ↓

D = 4 cause once you do all the cancellations it basically leads 2 D then you have to divide →→ 12/3 → 3·4 or 4·3 either way it equals 12 sooo just do the math and you will come up with ...............................↓

-Hope this helped you any if not so comment right answer D=4 :)
