Answer:

21y² +34 yx + 8x²

Step-by-step explanation:

Area of a rectangle is given by L×W where L is length, and W is width

Given L=3y+4x

          W=7y+2x

Area= (3y+4x) × (7y+2x)

          3y(7y+2x) + 4x(7y+2x)

           21y² + 6yx +28yx+8x²

            21y² +34 yx + 8x²

Bas_tet [7]

Step-by-step explanation:

a.) the given term can be written as

=

\sqrt{3}  \times  \sqrt{3 \times 2}

=

\sqrt{3 \times 3 \times 2}

=

3 \sqrt{2}

hence the given term is

3 \sqrt{2}

where b = 3

b.)

=

\sqrt{8}  \times  \sqrt{18}

=

\sqrt{2 \times 2 \times 2}  \times  \sqrt{2 \times 3 \times 3}

=

\sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3}

=

12

hence the given term is 12

If a = 3 what is the value of b in the equation 2a+b=13? And can you explain?
sladkih [1.3K]

Answer:

b=7

Step-by-step explanation:

Plug 3 into a since a=3.

2(3)+b=13

Then solve for 2(3)

6+b=13

Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)

b=13-6

b=7

If the signs of the coordinates of collinear points P(-6,-2), Q(-5,2), and R (-4,6) reversed, are the 3 new points still colline
Strike441 [17]

If all the points have the signs reversed, therefore this means that the whole line is reflected about an axis. Since all are reflected therefore this further means that the new points are still collinear.

 

We can prove this by plotting the points:

P’(6,2), Q(5,-2), R(4,-6)

<span>From the graph, they are in 1 line hence collinear.</span>
