Answer:

See explanation

Step-by-step explanation:

1.

(a+b)(a^2-ab+b^2)=a^3-a^2b+ab^2+a^2b-ab^2+b^3=a^3+b^3

2.

(1-7x)(1+9x)=1+9x-7x-63x^2=-63x^2+2x+1

3.

(x+y+3)(x+y-4)=x^2+xy-4x+xy+y^2-4y+3x+3y-12=x^2+2xy+y^2-x-y-12

4.

(a-b)(a^2+ab+b^2)=a^3+a^2b+ab^2-a^2b-ab^2-b^3=a^3-b^3

5.

(m^3n+8)(m^3n-5)=(m^3n)^2-5m^3n+8m^3n-40=m^6n^2+3m^3n-40

6.

(4-(3c-1))(6-(3c-1))=(4-3c+1)(6-3c+1)=(5-3c)(7-3c)=35-15c-21c+9c^2=9c^2-36c+35

7.

(ab-9)(ab+8)=(ab)^2+8ab-9ab-72=a^2b^2-ab-72

8.

(a+b-c)(a+b+c)=a^2+ab+ac+ab+b^2+bc-ac-bc-c^2=a^2+b^2-c^2+2ab

9.

(a+3)(a-2)=a^2-2a+3a-6=a^2+a-6

10.

(3m^3-y)(3m^3-y)=(3m^3)^2-3m^3y-3m^3y+y^2=9m^6-6m^3y+y^2

11.

(2x-3y)(4x-y)=8x^2-2xy-12xy+3y^2=8x^2-14xy+3y^2

12.

(x^2+2x-1)(x^2+2x+5)=x^4+2x^3+5x^2+2x^3+4x^2+10x-x^2-2x-5=x^4+4x^3+8x^2+8x-5

13.

(4x-3y+5)(x+2y-3)=4x^2+8xy-12x-3xy-6y^2+9y+5x+10y-15=4x^2+5xy-6y^2-7x+19y-15

Line F has a slope of. -6/3 and line G has a slope of -8/4.
Darina [25.2K]

Given:

Slope of line F = -\dfrac{6}{3}

Slope of line G = -\dfrac{8}{4}

To find:

The conclusion about distinct lines F and G.

Solution:

We have,

Slope of line F = -\dfrac{6}{3}

                        = -2

Slope of line G = -\dfrac{8}{4}

                        = -2

The slopes of lines F and G are equal and we know that the slopes of two parallel lines are always equal.

Therefore, the line F and line G are parallel to each other.
