Answer:

$287.50

Step-by-step explanation:

1st multiply $9.20 by 31 (which is equal to $285.20)

Marcus finds that (3x^2-2y^2+5x)+(4x^2+12y^2-7x)=7x^2-10y-2x. What error did Marcus make?
boyakko [2]

Answer:

7x^2+10y^2-2x is the correct answer, Marcus put -10y INSTEAD of +10y^2

Step-by-step explanation:

(3x^2-2y^2+5x)+(4x^2+12y^2-7x)

Combine like terms- I'll add x^2 first, then y^2, and then finally x, and it will be in that order.

7x^2+10y^2-2x

Make sure to check your signs are correct, and you wrote down the proper exponents.

The area of a square is increasing at the constant rate of 16sq.ft./min. When the perimeter of the square is 36ft, how fast is t
bixtya [17]

Answer:

The perimeter of square is increasing by 3.76ft/min and then by 3.4 ft/min.

Step-by-step explanation:

Given that area of square is increasing at a rate of 16 sq ft/min.

Given that final perimeter is 36ft

Perimeter of a square = 4 \times side = 36

So, side, a' = 9 ft

We know that area of a square is given by the formula:

A = side^2 = a^2 (If we let side = a units)

Change in area =

a'^2 - a^2\\\Rightarrow 9^2 - a^2 = 16\\\Rightarrow 81 - 16 = a^2\\\Rightarrow a = 8.06\ ft

So, side got changed from 8.06ft to 9 ft.

So, perimeter when side was 8.06 ft:

4 \times 8.06 = 32.24\ ft

Hence, increase in the perimeter when perimeter is 36 ft is = 36 - 32.24 = 3.76 ft

For finding Next increase:

area gets changed from 81 sq ft to 81+16 = 97 sq ft

So, new side = \sqrt{97} ft = 9.85 ft

Next increase in perimeter = 4 (New side - Old side)

= 4 (9.85 - 9)

= 3.4 ft/min
