Answer:

7 7/24

Step-by-step explanation:

first put the wholes inside the fraction:

1 \frac34 = \frac44 + \frac34 = \frac74

4 \frac16 = \frac{24}{6} + \frac16 = \frac{25}{6}

Then multiply numerator times numerator, denominator times denominator and take out wholes again:

\frac74 \times \frac{25}{6} = \frac{7 \times 25}{4 \times 6} = \frac{175}{24} = 7 \frac{7}{24}

How do I I solve this equation? <br>-18 = x/3 + 3
LuckyWell [14K]

Subtract 3 from both sides

-18 - 3 = x/3

Simplify -18 - 3 to -21

-21 = x/3

Multiply both sides by 3

-21 * 3 = x

Simplify -21 * 3 to -63

-63 = x

Switch sides

<u>x = -63</u>

Westkost [7]

The second-quadrant angle is

... arctan(3.3/-6.0) ≈ 151°

_____

Your calculator will tell you it is about -28.81°. You need to add 180° to that 4th-quadrant angle to put it in the 2nd quadrant.

Factor completely. (x^2 – 4)(x^2 + 6x + 9)<br>​
sertanlavr [38]
<h3>Answer:   (x-2)(x+2)(x+3)(x+3)</h3>

This is the same as (x-2)(x+2)(x+3)^2. The order of the factors doesn't matter.

===============================================

Explanation:

x^2-4 factors to (x-2)(x+2) after using the difference of squares rule

x^2+6x+9 factors to (x+3)(x+3) after using the perfect square trinomial factoring rule

So overall, the original expression factors to (x-2)(x+2)(x+3)(x+3)

We can condense this into (x-2)(x+2)(x+3)^2 since (x+3)(x+3) is the same as (x+3)^2

-------------------

Side notes:

  • Difference of squares rule is a^2 - b^2 = (a-b)(a+b)
  • The perfect square trinomial factoring rule is a^2+2ab+b^2 = (a+b)^2
