elixir [45]2 years ago
7 0

Answer:

C  2(z+3)

Step-by-step explanation:

z+(z+6)

Combine like terms

2z+6

We can factor out a 2 from each term

2(z+3)

Someone help me please. I don't just want the answer, I need an explanation on how it's done too.​
NARA [144]

Answer:

Below.

Step-by-step explanation:

f) (a + b)^3 - 4(a + b)^2  

The (a+ b)^2 can be taken out to give:

= (a + b)^2(a + b - 4)

= (a + b)(a + b)(a + b - 4).

g)  3x(x - y) - 6(-x + y)

=  3x( x - y) + 6(x - y)

= (3x + 6)(x - y)

= 3(x + 2)(x - y).

h) (6a - 5b)(c - d) + (3a + 4b)(d - c)

=  (6a - 5b)(c - d) + (-3a - 4b)(c - d)

= -(c - d)(6a - 5b)(3a + 4b).

i)  -3d(-9a - 2b) + 2c (9a + 2b)

= 3d(9a + 2b) + 2c (9a + 2b)

=  3d(9a + 2b) + 2c (9a + 2b).

= (3d + 2c)(9a + 2b).

j)  a^2b^3(2a + 1) - 6ab^2(-1 - 2a)

=  a^2b^3(2a + 1) + 6ab^2(2a + 1)

= (2a + 1)( a^2b^3 + 6ab^2)

The GCF of a^2b^3 and  6ab^2 is ab^2, so we have:

(2a + 1)ab^2(ab + 6)

= ab^2(ab + 6)(2a + 1).

Answer:

Step-by-step explanation:

i'll do a few of them

1)   one inch plus a half inch plus an eighth inch plus a sixteenth inch

     1 + 1/2 + 1/8 + 1/16         read the tick marks

     1 + 8/16 + 2/16 + 1/16    find a common denominators

     1 and 11/16                    add the sixteenth numerator

2)

3)

4)  6 inch  plus an eighth inch plus a sixteenth inch

     6 +  1/8 + 1/16         read the tick marks

     6 + 2/16 +  1/16       find a common denominators

     6 and 3/16              add the sixteenth numerator

5)   nine inch plus a quarter inch plus an eighth inch

     9  + 1/4 + 1/8          read the tick marks

     9 + 2/8 + 1/8          find a common denominators

Find f(-1), f(0), f(3) for the following function.<br> f(x)=3x<br> f(-1)=Blank
kramer

Answer:

If f(x) = 3x, this means that any number that replaces x in the parenthesis, would replace x in the right side too.

When x = -1:

f(-1) = 3(-1) = -3

When x = 0:

f(0) = 3(0) = 0

When x = 3:

f(3) = 3(3) = 9

Is -8-2(3+2n)+7n equivalent to -30-13n. Explain why or why not.
seropon [69]

No, -8 - 2(3 + 2n) + 7n is not equivalent to -30 - 13n

Step-by-step explanation:

Let us revise the operation of the negative and positive numbers

  • (-) + (-) = (-)
  • (-) × (-) = (+)
  • (-) + (+) = the sign of greatest [(-) if the greatest is (-) or (+) if the greatest is (+)]
  • (-) × (+) = (-)
  • (-) - (+) = (-)
  • (+) - (-) = (+)

∵ The expression is -8 - 2(3 + 2n) + 7n

- Simplify it

∵ 2(3 + 2n) = 2(3) + 2(2n) = 6 + 4n

∴ -8 - 2(3 + 2n) + 7n = -8 - (6 + 4n) + 7n

- Multiply the bracket by (-)

∴ -8 - (6 + 4n) + 7n = -8 - 6 - 4n + 7n

- Add the like terms

∴ -8 - (6 + 4n) + 7n = (-8 - 6) - 4n + 7n

∴ -8 - (6 + 4n) + 7n = -14 + 3n

∴ -8 - 2(3 + 2n) + 7n is equivalent to -14 + 3n

∵ -14 + 3n ≠ -30 - 13n

∴ -8 - 2(3 + 2n) + 7n is not equivalent to -30 - 13n

No, -8 - 2(3 + 2n) + 7n is not equivalent to -30 - 13n
