Step-by-step explanation:

1.x^2+7x+12

find two numbers that multiply to give the constant by the coefficient of x squared and when added will give you 7 x . the numbers are 3 and 4

(x^2+4x)+(3x+12)

x(x+4)+3(x+4)

(x+4) and(x+3) are the factors

2.4x^2+6x+2

(4x^2+2x)+(4x+2)

2x(x+1)+2(x+1)

(x+1) and(2x+2) are the factors.

Step-by-step explanation:

x2 + 7x + 12

x2 + 4x + 3x + 12

x(x + 4) + 3( x + 4)

(x + 3) and (x + 4) are the factors

4x2 + 6x + 2

4x2 + 4x + 2x + 2

4x (x + 1) + 2(x + 1)

(x + 1) and (4x + 2) are the factors

Triangle ABC has vertices A (1,1), B (3,2) and C (0,-2), It is dilated by a scale factor of 1/2 about the origin to create trian
Ghella [55]

Answer:

The length is 2.5 units

Step-by-step explanation:

Before we find the value of the length of the side, we need the measure of the coordinates after dilation

B’ = 1/2 B = 1/2(3,2) = (1.5, 1)

C’ = 1/2 C = 1/2( 0,-2) = (0,-1)

The measure of the length is the distance between the two points

Mathematically, that would be;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(0-1.5)^2 + (-1-1)^2

D = √(2.25 + 4)

D = √6.25

D = 2.5 units

Rus_ich [418]

Answer: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score are 720 which is considered a good payment point.

Explanation: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score is 720 which is considered a good payment point.

Explanation: Credit score is known as CIBIL. By this credit, score banks gauge the creditworthiness of a person. The data listed in our credit report CIBIL generate our credit score.

A person's credit history is submitted to CIBIL by banks and other financial institutions on a particular basis.

For example, if a person has a credit score of 600 then that person cannot be considered a good creditor. In this case, the bank doesn't lend him  .
