7x - 1 + 6x - 1 = 180

add the x’s, add the numbers

13x - 2 = 180

add 2 to 180

13x = 182

divide 182 by 13

x = 14

Answer:

Step-by-step explanation:

7x -1 +6x -1 = 180, group like terms

7x+6x -1 -1 = 180, combine like terms

13x -2 = 180, add 2 to both sides

13x -2+2 = 180+2 , solve the additions

13x = 182, divide both sides by 13

13x/13 = 182/13, solve the divisions

x = 14

How do i solve this quadratic equation x²+6x+c

Anuta_ua [19.1K]

recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.

$\bf 6x=2\cdot \sqrt{x^2}\cdot \sqrt{c}\implies 6x=2\sqrt{x^2c}\implies 6x=2x\sqrt{c}\\\\\\\cfrac{6x}{2x}=\sqrt{c}\implies 3=\sqrt{c}\implies 3^2=c\implies 9=c$

Find a polynomial f(x) of degree 4 that has the following zeros. 7, −3, 0, −2

HACTEHA [7]

Answer:

x^4 - 2x^3 - 29x^2 - 42x

Step-by-step explanation:

Equal all the zeros to x then move them over.

x=7,x=-3,x=0,x=-2

x-7,x+3,x+0,x+2

Then multiply each factor

(x-7)(x+3)(x)(x+2)

x^4 - 2x^3 - 29x^2 - 42x
