Simplify expression 1/4 •3(8a-5b-4)-(4a+1)+4b
pychu [463]

Answer:

(8a+b-16)/4

Step-by-step explanation:

1/4×3(8a-5b-4)-(4a+1)+4b

Simplify:

-4a-1+4b+1/4×3×8a-1/4×3×5b-1/4×3×4

=1/4xax24-4a-1/4bx15+4b-1/4×12-1

=1ax24/4 -4a - 1bx15/4 +4b -1×12/4 -1

=ax24/4 -4a -bx15/4 + 4b -12/4 -1

= -4a + 24a/4 + 4b - 15b/4 -1 -3

= -4a + 6a + 4b - 15b/4 - 4

= 2a + 4b - 15b/4 - 4

= 8a + 16b - 15b - 16 / 4

= (8a + b - 16) / 4

= 8a + b - 16 / 4

4+x^2=7x standard form
EastWind [94]

For standard form, we have to rearrange this equation. We want the variables on one side (also called Slope Intercept Form or Ax + By = C)

Subtract 7x from both sides and 4 from both sides to "swap" the variables and the constant number.

This gives us:

x^2 - 7x = -4
