Answer:

3x²-10x+8

Step-by-step explanation:

To simplify the expression we need to multiply each term in the first bracket with the expression in the second bracket.

x(3x-4)-2(3x-4)

3x²-4x-6x+8

Executing the operations to give a quadratic expression we get:

3x²-10x+8

The simplified expression is therefore

3x²-10x+8

Answer:  3x^2-10x+8

Step-by-step explanation:

Given the expression (x-2)(3x-4), you can apply Distributive property to simplify it. But first, you must remember the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

Then:

(x-2)(3x-4)=(x)(3x)+(x)(-4)+(-2)(3x)+(-2)(-4)=3x^2-4x-6x+8

The final step is to add the like terms. Therefore, you get:

3x^2-10x+8

And the square root of 7 is a random decimal, so it is irrational.

A) write 63 as the product of prime numbers.
steposvetlana [31]

63 as the product of prime numbers is 3 x 3 x 7.

The highest common factor of 63 and 105 is 21.

Prime numbers are numbers that are only divisible by one and that number. Examples of prime numbers are 5, 7, and 11.

Factors of 63 are: 1, 3, 7, 9, 21, and 63

Prime numbers that are products of 63 = 3 x 3 x 7

The factor of a number is a number that can divide another number without leaving any remainder.

  • Factors of 63 =  1, 3, 7, 9, 21, and 63
  • Factors of 105 =  1, 3, 5, 7, 15, 21, 35 and 105.
  • Common factors = 1, 3, 7, 21
  • Highest common factor = 21
