Answer:

(x - 2)(x + 1)(2x -1)

Step-by-step explanation:

We use synthetic division as a tool for factoring the given expression.  The coefficients of the terms given are {2, -3, -3, 2}.  If x - 2 is a factor of this expression, then 2 is a root.  We perform synthetic division as follows:

2   /    2     -3      -3     2

                  4       2     -2

    -------------------------------

          2      1        -1      0

Next, we determine whether or not (2x - 1)(x + 1) represents the remaining factor(s).  Using -1 as divisor, we get:

-1    /     2     1     -1

                   -2    1

     ---------------------

             2     -1     0

Since the remainder is zero, x + 1 must be a factor and (2x - 1) the third factor.  Answer D is correct.

Amanda bought 4 shirts and 9 skirts for $168.75. On another day she bought 3 shirts and 12 skirts for $172.50. How much did she
Karolina [17]

Answer:shirt = $22.5

skirt= $8.75

Step-by-step explanation:

Let shirt be x and skirt be y

4x + 9y = 168.75--------1

3x + 12y = 172.5---------2

Using elimination method

Multiply eqn 1 by 3 and eqn 2 by 4

12x + 27y= 506.25

12x + 48y = 690

Subtracting

-21y = -183.75

y = $8.75

Put in eqn 1

4x + 9×8.75 = 168.75

4x = 168.75 - 78.75

4x = 90

x = $22.5

How do you find the answers to g, h, I, and j?
Daniel [21]

its in vertex form

-3 means is open down or looks like this ∩

the vertex is (-2, 7)  - opposite of the number in brackets and the constant 7

so it increases from - ∞ to -2 and decrease after

g) - ∞ to -2

h)   -2 to ∞

i)  at the ends it points down to - ∞

j)  multiply is out at put it in ax² +bx + c standard form, its in vertex
