1.(8x+3)(4x-5) 2.(10x-2)(3x+6) show your work will mark brainliest

1)

32x^2 - 28x - 15

2)

30x^2 + 54x - 12

Step-by-step explanation:

1.

(8x+3)(4x-5)

Using FOIL

= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)

= 32x^2 - 40x + 12x - 15

= 32x^2 - 28x - 15

2.

(10x-2)(3x+6)

Using FOIL

= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)

= 30x^2 + 60x - 6x - 12

= 30x^2 + 54x - 12

2. A) 4 and B)

3. A) and B) 1

4. A) -9 and B) 12

Step-by-step explanation:

Solve for y

anything in front of x is the slope and contants are the y-intercepts
