The Order of Operation can be remembered by PEMDAS

Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction

and you follow it from left to right.

Order of Operations is a very important math concept to understand. Order of Operations is a set of math rules that tell you which math operations like addition or multiplication to do first. If you always follow the rules that go along with Order of Operations, you will always get the same answer. They are 4 rules.

First: Parentheses and Brackets

Next: Exponents

Then: Multiplication and Division

Last: Addition and Subtraction

Answer:

(6x - 1) • (2x + 9)

Step-by-step explanation:

STEP

Equation at the end of step 1

((22•3x2) + 52x) - 9

STEP

Trying to factor by splitting the middle term

2.1 Factoring 12x2+52x-9

The first term is, 12x2 its coefficient is 12 .

The middle term is, +52x its coefficient is 52 .

The last term, "the constant", is -9

Step-1 : Multiply the coefficient of the first term by the constant 12 • -9 = -108

Step-2 : Find two factors of -108 whose sum equals the coefficient of the middle term, which is 52 .

-108 + 1 = -107

-54 + 2 = -52

-36 + 3 = -33

-27 + 4 = -23

-18 + 6 = -12

-12 + 9 = -3

-9 + 12 = 3

-6 + 18 = 12

-4 + 27 = 23

-3 + 36 = 33

-2 + 54 = 52 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 54

12x2 - 2x + 54x - 9

Step-4 : Add up the first 2 terms, pulling out like factors :

2x • (6x-1)

Add up the last 2 terms, pulling out common factors :

9 • (6x-1)

Step-5 : Add up the four terms of step 4 :

(2x+9) • (6x-1)

Which is the desired factorization

HOPE IT HELPS! :))

Triangle ABC is similar to triangle DEC, ∠B ≅ ∠E and 3DE = 2BC

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>rotation, reflection, translation and dilation.</em>

Dilation is the increase or decrease in the size of a figure by a scale factor.

Right triangle ABC is reflected over AC, then dilated by a scale factor of 2/3 to form triangle DEC, hence:

Triangle ABC is similar to triangle DEC, corresponding angles are congruent (∠B ≅ ∠E) and DE = (2/3)BC i.e. 3DE = 2BC
