Answer:

The 2 solutions are 0 and 3,

Step-by-step explanation:

– x2 + 4x + 1 = x + 1

-x^2 + 3x = 0

x(-x - 3)

x = 0 or -x - 3 = 0 which gives x = 3.

Answer:

x = 0 or x = 3

Step-by-step explanation:

if f(x) = g(x) then – x2 + 4x + 1 = x + 1

add the like terms

-x^2 +3x = 0

-x (x-3) = 0 then x is either 0 or 3

12x - 5 = 8x - x + 50 Help please show work and check the solution

Inga [223]

Answer:

x = 11

Step-by-step explanation:

$12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11$

and check:

$12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127$

I need some help please

gizmo_the_mogwai [7]

Answer:

a) -10

b) 7

Step-by-step explanation:

a) $2(x + 3) = x - 4$

$= > 2x + 6 = x - 4$

$= > 2x - x = - 4 - 6$

$= > x = - 10$

b) $4(5x - 2) = 2(9x + 3)$

$= > 20x -8 = 18x + 6$

$= > 20x - 18x = 8 + 6$

$= > 2x = 14$

$= > x = \frac{14}{2} = 7$
