(6x+3)(6x-3)

Step-by-step explanation:

I used FOIL

Multiply the first numbers 6x*6x=36x^2

The outer -18x

Inner 18x which the outer and the inner cross out

Last 3*-3=-9

36x^2 -9

Answer:

(6x+3) (6x—3)

Step-by-step explanation:

(6x + 3) (6x—3)

(6x • 6x ) + (6x • -3) + (3 • 6x) + (3• -3)

            36x² -18x + 18x -9

                    36x²-9

The diagonals of a quadrilaretral intersect at (-1,4). One of the sides of the quadrilateral is bounded by (2,7) and (-3,5)
Maurinko [17]

Solution:

Properties of Square

1. All sides are equal.

2. Opposite sides are parallel.

3. Diagonals are equal and bisect each other at right angles.

As, given point of intersection of diagonals of square is (-1,4).

And, One of the sides of the quadrilateral is bounded by (2,7) and (-3,5).  

Drawn the picture of square below,

Let, the third and fourth vertices of square be (x,y) and (p,q).

As, diagonals of square bisect each other. So,

\frac{x+2}{2}=-1\\\\ x +2=-2\\\\ x=-2-2\\\\ x=-4\\\\ \frac{y+7}{2}=4\\\\ y+7=8\\\\ y=8-7\\\\ y=1\\\\ \frac{p-3}{2}=-1\\\\ p-3=-2\\\\ p=3-2\\\\ p=1 \\\\ \frac{q+5}{2}=4\\\\ q+5=8\\\\ q=8-5\\\\ q=3

So, third and fourth vertices are (-4,1) and (1,3).

Gekata [30.6K]

Answer:

3(-9+17)

Distributive property:

3*-9

3*17

3 times -9 is -27

and 3*17 is 51

you are left with -27+51

now you add and get 24

you could also use PEMDAS

do 3(8)

and get 24

So your answer is 24, Hope that helps!
