Answer:

b=-3

Step-by-step explanation:

4b+3=-9

    -3   -3

subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.

4b=-12

youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4

4b/4=-12/4

4b divided by 4 is 1. -12 divided by 4 is -3

b=-3

plug -3 in for b to make sure its correct

4(-3)+3=-9

-12+3=-9

-9=-9

Simplify the polynomial expressions by combining like terms, and then multiply the resulting binomial expressions to find their
Lesechka [4]
For this case we have the following expression:
 (8x - 9 - 2x) (15 + 5x - 5)

 The first thing we must do is to rewrite the expression as the product of two binomials.
 To do this, we add similar terms.
 We have then:
 (6x - 9) (5x + 10)

 Then, doing distributive property we have:
 30x ^ 2 + 60x - 45x - 90

 Adding similar terms:
 30x ^ 2 + 15x - 90
 Answer:
 
The simplified expression is:
 
30x ^ 2 + 15x - 90
