mariarad [96]2 years ago
4 0

Step-by-step explanation:

find the Lcm of 15 and 10 which is 30

multiply the 2fractions by the LCM

8/15*30=16

3/10*30=9

add the products and put them all over the Lcm

(16+9)/30

=25/30 which is equivalent to 5/6 when you divide both the numerator and the denominator by 5

Write the written form of the following expressions given in the symbolic form, then simplify each expression.
miss Akunina [59]

The values of the equation will be:

9. 12x - 1

10. -50 - x

11. -x + 14

12. x³ - 4y - 4

13. 8 - 6x

14. 288 - 1080x

15. 420 - y

16. 66 + 7y - 9x

<h3>How to compute the equation?</h3>

9. 4(3x+ 2) - 9

12x + 8 - 9

12x - 1

10. √144 – (62 –x)

12 - (62 - x)

-50 - x

11. (28 ÷ 4) – (x + 7)

7 - x + 7

= -x + 14

12. x³ – 4y - (6 + 2)

x³ - 4y - 4

13. 64 ÷ 8) – (x • 6)

= 8 - 6x

14. 72 (4 - 15x)

288 - 1080x

15. 4(√144 + 93)–y

4(12 + 93) - y

= 420 - y

16. 54 + 7y – (8 + 9x)

= 66 + 7y - 9x

Find the number that must be added to each expression to form a perfect square trinomial. Then write the trinomial as a binomial
maksim [4K]
<h2>Hello!</h2>

The answers are:

a) \frac{49}{4}

b) (x+\frac{7}{2})^{2}

<h2>Why?</h2>

First, we need to know that for this case:

a=1\\2ab=7

So,

b=\frac{7}{2}

b^{2} =(\frac{7}{2})^{2}=\frac{49}{4}

We must add \frac{49}{4}  to the expression in order to form a perfect square trinomial,

x^{2} +7x+\frac{49}{4}

Writing the trinomial as a binomial square:

(x+\frac{7}{2})^{2}=x^{2}+2*\frac{7}{2}*x+(\frac{7}{2})^{2}=x^{2} +7x+\frac{49}{4}

Have a nice day!
