1 answer:

4 0

The sum is the total of the given values being added.
Given the expressions above, to add them, you just have to add the numbers with the same terms. 13x2 and 8x2 have the same terms which is x2, therefore, you can add both and the result is 21x^2 then just copy 5x so the sum would be 21x2 + 5x. Hope this answer helps.

1/4 x 2/5 x 3/6 x 4/7 x 5/8 x 6/9 x 7/n=?

postnew [5]

Answer:

c. $\frac{1}{12n} = {[12n]}^{-1}$

Step-by-step explanation:

$[\frac{1}{4}][\frac{2}{5}][\frac{1}{2}][\frac{4}{7}][\frac{5}{8}][\frac{2}{3}][\frac{7}{n}] = \frac{560}{6720n} = [12n]^{-1} = \frac{1}{12n}$

$\frac{2}{3} = \frac{6}{9}\\ \\ \frac{1}{2} = \frac{3}{6}$

* To make this simpler, reduce these two fractions in lowest terms.

I am joyous to assist you anytime.

Simplify: (7+2a)·3–20 =

Black_prince [1.1K]

<h2>Greetings!</h2>

Answer:

6a + 1

Step-by-step explanation:

First, you need to multiply everything in the brackets by 3L

(7 + 2a) x 3 =

7 * 3 = 21

2a * 3 = 6a

21 + 6a

Now you can subtract the 20 from this:

6a + 21 - 20

Simplified down:

6a + 1
