Answer:

The answer to your question is below

Step-by-step explanation:

1.- (2b - 1) (b + 8) = 0

    2b - 1 = 0           b + 8 = 0

     b = 1/2              b = -8

2.- (x + 3)(x - 12) = 0

     x + 3 = 0            x - 12 = 0

     x = -3                  x = 12

3.- (4b+ 7)(b + 11)

    4b + 7 = 0           b + 11 = 0

      b = -7/4             b = -11

4.- (k - 8)(k + 6)

     k - 8 = 0             k + 6 = 0

    k = 8                   k = -6

5.- (2n + 12)(5n+ 10)

     2n + 12 = 0             5n + 10 = 0

       n = -12/2 = -6          n = -10/5 = -2

6.- (w - 3)(3w - 7)

      w - 3 = 0                3w - 7 = 0

      w = 3                        w = 7/3

7.- (6n - 5)(n - 10)

     6n - 5 = 0                n - 10 = 0

      n = 5/6                   n = 10

8.- (n + 12)((4n + 7)

     n + 12 = 0                 4n + 7 = 0

     n = -12                         n = -7/4

9.- (3b + 4)(5b - 10)

      3b + 4 = 0                 5b - 10 = 0

       b = -4/3                     b = 10/5 = 2

10.- (p - 6)(p + 10)

       p - 6 = 0                  p + 10 = 0

       p = 6                        p = -10

Please helppp it’s confusing!!!
Valentin [98]

Answer:

First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))

So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).

So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.

Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3

In short,  3(2^0) = 3

(7y <br> 3<br> −2y <br> 2<br> +5) + (4y <br> 3<br> −3y)
alexira [117]

Answer:

26 y + 5

Step-by-step explanation:

Simplify the following:

7 3 y + 4 3 y - 3 y - 2 2 y + 5

7×3 = 21:

21 y + 4 3 y - 3 y - 2 2 y + 5

-2×2 = -4:

21 y + 4 3 y - 3 y + -4 y + 5

4×3 = 12:

21 y + 12 y - 3 y - 4 y + 5

Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:

(21 y - 4 y + 12 y - 3 y) + 5

21 y - 4 y + 12 y - 3 y = 26 y:

Answer: 26 y + 5
