Answer:

$- \frac{25}{4}$

Step-by-step explanation:

$\frac{1}{2} -3 (\frac{1}{2} + 1)$ ²

Calculate sum

$\frac{1}{2} -3x (\frac{3}{2})$ ²

To raise a fraction to a power raise numerator and denominator to that power

$\frac{1}{2}$ -3 x $\frac{9}{4}$

Calculate product

$\frac{1}{2}$ - $\frac{27}{4}$

Subtract fractions

- $\frac{25}{4}$

What is the value of x? Use an informal argument to justify your answer *

Answer:

68°+47°+ x = 180°

115°+ x = 180°

115°-115°+x = 180°-115°

x = 65°

hope it's helpful ❤❤❤❤

This is how I find the GCF.

I find the prime factors.

63/3 = 21
21/3 = 7
7/7 = 1

81/3 = 27
27/3 = 9
9/3 = 3
3/3 = 1

Then I find the common prime factors:
63: 3 x 3 x 7
81: 3 x 3 x 3 x 3

Then I multiply the common prime factors:
3 x 3 = 9

The GCF for 63 and 81 (number 3) is 9.

I bet you can use this method for all the other GCFs! :)

For this one, find the prime factors like before, and if there aren't any besides one, then it's a prime number.

75/3 = 25
25/5 = 5
5/5 = 1

The prime factorization for 75 is 3 x 5 x 5

(I don't know the answer to 7, 8, 9, 10, 11, 12, 25, or 26, sorry!)
