Answer:

25 black and 11 white

The area of a rectangle is 28 m', and the length of the rectangle is 1 m more than twice the width. Find the dimensions of the r
Marianna [84]

Answer:

8m ×3.5m

Step-by-step explanation:

Area of rectangle= length ×width

Let the length and width of the rectangle be L and W meters respectively.

Area of rectangle= LW

LW= 28 -----(1)

L= 2W +1 -----(2)

Subst. (2) into (1):

(2W +1)(W)= 28

<em>Expand:</em>

2W² +W= 28

<em>-28 on both sides:</em>

2W² +W -28= 0

<em>Factorise</em><em>:</em>

(W +4)(2W -7)= 0

W +4=0 or 2W -7=0

W= -4 (reject) or W= 3.5

Substitute W= 3.5 into (2):

L= 2(3.5) +1

L= 7 +1

L= 8

∴ The dimensions of the rectangle is 8m ×3.5m.

Is the equation true, false, or open? 5x+2=6x+11
ICE Princess25 [194]
I think your suppose to combine like terms to find your answer.... Like for example 5x+2=6x+11
what I did first was combine my x's which is 5x+6x is 11x
then I added 2+11 and that gave me 13 so I put it together and got 11x+13
