Answer:

4,9 and 4,-9 is different because 4,9 doesn't have no - (minus)

While 4 -9 have a subtraction sign. I don't if this is right. But I hoped this helped :)

Answer:

(4,9) is in quarter I and (4,-9) is in quarter IV of the graph. (4,-9) is the point (4,9) reflected over the x-axis. they are similar bc both have 4 as their x coordinate.

A spark plug listed at $1.89, marked down 29%
N76 [4]
29% = 0.29

Multiply 1.89 with 0.29

1.89 x 0.29 = 0.5481

Note that it is a markdown, so subtract 0.55 (rounded) with 1.89

1.89 - 0.55 = 1.34

The spark plug now costs ~ $1.34

hope this helps

That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.

kkurt [141]

Answer:

A. =(9x-12)^2

Step-by-step explanation:

We need to determine whether the polynomial 81x^2-216x+144 can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

81x^2-216x+144

=9(9x^2-24x+12)

=9(9x^2-12x-12x+12)

=9(3x(3x-4)-4(3x-4))

=9(3x-4)(3x-4)

=9(3x-4)^2

=3^2(3x-4)^2

=(3(3x-4))^2

=(9x-12)^2

Hence choice A. =(9x-12)^2 is correct.

Use proportion to find the answer.
prisoha [69]

<u>Answer</u>

\boxed {64}


<u>Detailed Explanation </u>

Let's set up a proportion.


\frac{3}{4.8} = \frac{40}{x}


Now that we have set up a proportion we would need to cross multiply.

3*x=3x

40*4.8= 192


Solve for x

3x=192


\frac{192}{3} = 64


Therefore, the answer would be 64.
