Combine the x together and combine the y together
So 4x-3x=x, 2y+5y=7y
So the answer will be x+7y+2

A lumber yard has five different lengths of 2 by 4 boards. Based on cost per linear foot, which is the best deal available on 2 by 4 boards at this lumber yard?

2 × 4 BOARD PRICES

8 foot board for $2.95

10 foot board for $3.15

12 foot board for $4.10

16 foot board for $5.80

20 foot board for $6.95

Step-by-step explanation:

8 foot board for $2.95

$\frac{2.95}{8}= 0.36875$

10 foot board for $3.15

$\:\frac{3.15}{10}=0.315$

12 foot board for $4.10

$\frac{4.1}{12}=0.341$

16 foot board for $5.80

$\frac{5.8}{16}= 0.3625$

20 foot board for $6.95

A border of uniform width is placed around a rectangular photograph that measures 8 inches by 10 inches. If the area of the bord

amid [387]

Answer:

width of the border is 3 inches

Step-by-step explanation:

Given data

size = 8 inches by 10 inches

area = 144 square inches

to find out

width of the border

solution

first we consider width of border is x

area of new full rectangle = (8 + 2x ) × ( 10 + 2x )

so we know area of photo = 8 × 10 = 80 square inches

and area of border = 144 square inches that is given

so new area of photo with the border is 80 + 144 = 224 square inches

and we can say that

area of full rectangle - area of the photograph = Area of Border

(8 + 2x) × (10 + 2x) – (80) = 144 square inches

80 + 16x + 20x + $4x^{2}$ – 80 = 144

$4x^{2}$ + 36x – 144 = 0

solve thios equation we get

$2x^{2}$ + 9x – 36 = 0

solve thios equation we get

(x + 12) (x – 3) = 0

so here x have two value one is negative and other is positive

so we consider only positive value

x = -12 or x = 3

width of the border is 3 inches
