Nine times a number added to a subtracted from triple the sum of seven times the number 9

navik [9.2K]

Answer:

16x + 19

Step-by-step explanation:

Let's say number = x

two times a number = 2x or 2*x

added to -3 = 2x - 3

subtracted from twice the sum of nine times the number and 8

2(9x + 8) - (2x - 3)

Combining like terms

18x + 16 - 2x + 3

16x + 19

Please help me with this question, will give brainliest.

Ugo [173]

Answer:

See below.

Step-by-step explanation:

A difference of squares is a quadratic written in the form $a^2-b^2$ . This form occurs naturally when distributing binomials.

$(2x-3)(2x+3)\\4x^2-6x+6x+-\\4x^2 - 9\\(2x)^2 - 3^2$

The difference of squares formula is

$a^2-b^2 = (a-b)(a+b)$

Example:

$m^2 - 16y^2=(m-4y)(m+4y)$

$x^2-36 = (x-6)(x+6)$
