Answer:

a = 3, b = -4, c = -20

Step-by-step explanation:

<u>Step 1:  Find the a, b, and c values</u>

ax^2 + bx +  c = 0

3x^2 - 4x - 20 = 0

The a value is:  3

The b value is:  -4

The c value is:  -20

Answer:  a = 3, b = -4, c = -20

If x² + xy – 3y = 3, then at the point (2, 1), dy/dx
Scilla [17]

Answer:

A

Step-by-step explanation:

We have the equation:

x^2+xy-3y=3

Take the derivative of both sides with respect to x:

\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]

Implicitly differentiate:

2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0

Solve for dy/dx:

\frac{dy}{dx}(x-3)=-2x-y\\

Divide:

\frac{dy}{dx}=-\frac{2x+y}{x-3}

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5

Hence, our answer is A.

The base is a square 16m 6m
Ostrovityanka [42]

base is a square 16m 6m

Step-by-step explanation:

A square is a regular quadrilateral and it has four equal sides and four equal angles (90 degree angle or right angles).

A square quadrilateral with vertices ABCD would be denoted by ABCD. The perimeter of a square (quadrilateral) is given by:

P = 4a

Where a is the length of each side.

Perimeter of the square:

P = 4a

P = 4 × 16 cm

P = 64 cm

Hence, the perimeter of square is 64 cm.
