Question:

Which expressions are equivalent to 8(-10x+3.5y-7)? Select two options.

Answers

-80x + 28y - 424(-20x + 7y - 14)

Step-by-step explanation:

Use the distributive property a(b + c) = ab + ac:

8( -10x + 3.5y - 7)

= (8)(-10x) + (8)(3.5y) + (8)(-7)

= -80x + 28y - 42

8(-10x + 3.5y - 7)

= (4)(2)(-10x + 3.5y - 7)

= 4[(2)(-10x) + (2)(3.5y) + (2)(-7)]

= 4(-20x + 7y - 14)

the real answer is -80x+28y-56

Step-by-step explanation: Hope this help

4(-20x+7y-14) .. only one option correct

Step-by-step explanation:

8(-10x+3.5y-7) = -80x + 28y -56

4(-20x+7y-14) = -80x +28y -56

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

[tex]Which expressions are equivalent to 8(-10x+3.5y-7)[/tex]

For this case we must find an expression equivalent to:

[tex]8 (-10x + 3.5y-7) =[/tex]

We apply distributive property to each of the terms within the parentheses, then:

[tex]8 * (- 10x) + 8 * (3.5y) +8 * (- 7) =\\-80x + 28y-56[/tex]

Finally, an equivalent expression is:

[tex]-80x + 28y-56[/tex]

[tex]-80x + 28y-56[/tex]

pretty sure its the last 2

Step-by-step explanation:

−80x+28y−56  what you do is    =(8)(−10x+3.5y+−7)=(8)(−10x)+(8)(3.5y)+(8)(−7)=−80x+28y−56
