Check the picture below.

notice, the composite is just a parallelogram, in blue, with a base of 6 units and a height of 4 units, and a triangle, in yellow, of a base of 6 units and a height of 2 units.

recall the area of a parallelogram is base*height, and for a triangle is (1/2)bh.

so, we can simply get the area of both and sum them up.

\bf \stackrel{parallelogram}{6\cdot 4}~~+~~\stackrel{triangle}{\cfrac{1}{2}(6)(2)}

The ____ property allows you to regroup terms using parentheses when adding or multiplying
Vadim26 [7]

Answer:

  "associative"

Step-by-step explanation:

The associative property lets you change the grouping of terms of a sum or of a product.

___

For example, you can rewrite

  (5 + 4·3) -2

as

  5 + (4·3 -2)

but the associative property does NOT allow you to change the grouping to ...

  (5 +4)·3 -2 . . . . . not a valid rewrite

Solve −5x = 15. (1 point)<br><br><br> −3<br> 3<br> 10<br> 20
Luba_88 [7]
Remember you can do anything to an eqautoin as long as you do oit to both sides

-5x=15
try to get 1x by itself

remember
(ax)/a=x when a=a

so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3

answer is first one
x=-3

The simplified expression of \sqrt{\frac{162x^9}{2x^{27}}} is \frac{9}{x^9}

<h3>How to simplify the expression?</h3>

The expression is given as:

\sqrt{\frac{162x^9}{2x^{27}}}

Divide 162 and 2 by 2

\sqrt{\frac{81x^9}{x^{27}}}

Take the square root of 81

9\sqrt{\frac{x^9}{x^{27}}}

Apply the quotient rule of indices

9\sqrt{\frac{1}{x^{27-9}}}

Evaluate the difference

9\sqrt{\frac{1}{x^{18}}}

Take the square root of x^18

\frac{9}{x^9}

Hence, the simplified expression of \sqrt{\frac{162x^9}{2x^{27}}} is \frac{9}{x^9}
