You can sum like terms. Two terms can be summed if they are both constants (i.e. pure numbers) or if they involve the same powers of the same variable.

In this case, 3x and 13x can be summed because they both involve 'x' alone. The sum is

3x+13x = (3+13)x = 16x

As for the other two terms, you simply have to sum two numbers, as usual:

-9-6 = -15

So, the final answer is

16x-15

Answer:

Yes, these triangles are congruent

∠E≅∠M

Step-by-step explanation:

Yes, these triangles are similar.

<em>Proof:</em>

Each side in LNM is 1\frac{2}{3} times longer than the sides in GFE

30/18 = 1\frac{2}{3}

25/15=1\frac{2}{3}

20/12 = 1\frac{2}{3}

According CPCTC (corresponding parts of congruent triangles are congruent), angle E is similar to angle M.

Hope this helps :)

Have a good day!

What is 20 5/81 in simplest form
Marizza181 [45]
20 5/81 in its simplest form is 20 5/81.

20 5/81 originally looks like this ⇒ 1625/81

((20 * 81)+5)/81 = (1620+5)/81 = 1625/81   * this is an improper fraction because the numerator is greater than the denominator. Improper fractions must be converted to proper fractions. It will then become a mixed fraction.
 
     <u>  0020  5/81</u>        
81 | 1625
       <u>162      </u>      * 81 x 2
           05
