Trying to factor as a Difference of Squares:

2.1 Factoring: 9x ${}^{2}$ -1

Theory : A difference of two perfect squares, A ${}^{2}$ - B ${}^{2}$ can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A ${}^{2}$ - AB + BA - B2 =

A ${}^{2}$ - AB + AB - B2 =

A ${}^{2}$ - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 9 is the square of 3

Check : 1 is the square of 1

Check : x ${}^{2}$ is the square of x1

Factorization is : (3x + 1) • (3x - 1)

Final result :

(3x + 1) • (3x - 1)

⊙M≅⊙N and ZY=32.6. Identify ST rounded to the nearest tenth.

aalyn [17]

The measure of length ST will be 6.4 So option B is correct.

<h3>What is a circle?</h3>

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Given; M≅N and ZY=32.6

Identify ST;

Radius of the circle r = 24

We know that from pythagoras theorem;

ZP^2 + PM^2 = ZM^2

Also, 2 ZP = ZY

So,

16.3^2 + PM^2 = 24^2

PM^2 = 310.7

PM = 17.6

Since, M≅N then PM = SN.

therefore, SN = 17.6

ST = 24 - 17.6 = 6.4

Hence, The measure of length ST will be 6.4 So option B is correct.

I need help!. My daughters lesson is on improper Fractions and mixed numbers. I need the answers to all of these math problems a

Lerok [7]

When doing improper fractions, you're going to keep the denominator the same. For example in question number 6, there are 18 triangles filled in so the improper fraction would be 18/5. Mixed numbers consist of the number of whole numbers filled and the remainder in the fraction. Therefore number 7, mixed number is 2 3/5 and the improper fraction would be 13/5. I'll list the rest of the answers below:
8.) Mixed: 1 3/5 Improper: 8/5
9.) Mixed: 4 1/4 Improper: 17/4
10.) 5/4, 7/4
12.) 13/8, 7/4, 19/8, 5/2, 21/8
13.) 4/3, 17/9, 7/3

Note: You can simplify improper fractions, this is why you'll get different denominators on the number line questions.
