-3x + 4x + 2y - 3y = x - y.

4m - 6mn - 4m - mn = -7mn.

9g - 8h - 3h - 4g = 5g - 11h.

Hope this helps,

Suppose 2 eggs with bacon cost 2.70 . One egg with bacon costs 1.80 . At thesebrates what will bacon alone cost

Leno4ka [110]

If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.

Compute using significant digits. What is the area of a parallelogram with length 17.25 mm and width 5.065 mm?

Dmitriy789 [7]

Answer: Option 'a' is correct

Step-by-step explanation:

Since we have given that

Length of parallelogram =17.25 mm

Width of parallelogram =5.065 mm

As we know the formula for " Area of parallelogram"

Area of parallelogram is given by

$Area= length \times breadth\\\\17.25\times 5.065=87.03 \ mm^2$

Hence, option 'a' is correct .

Suzanne has a rectangular garden which is 18 feet long and 11 feet wide. She has 168 square foot of paving stones, and she wants

VikaD [51]

Answer:

width = 2.5 feet

Step-by-step explanation:

Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.

Area of the garden = length times width = 18 times 11= 198 square foot

Let 'w' be the width of the border

Length of the garden with border = 18+2w

Width of the garden with border = 11+2w

Area of the garden with border = $(18+2w)(11+2w)=4w^2+58w+198$

Area of the border = $4w^2+58w+198-198=4w^2+58w$

She has 168 square foot of paving stones,

$4w^2+58w=168$

Solve for w

apply quadratic formula

a= 4, b= 58 and c=-168

$\quad x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$w=\frac{-58+-\sqrt{58^2-4\cdot \:4\left(-168\right)}}{2\cdot \:4}$

$w=\frac{-58+-\sqrt{6052}}{8}$

we get two values for w

$w=\frac{-58+\sqrt{6052}}{8}=2.47$

$w=\frac{-58-\sqrt{6052}}{8}=-16.97$
