Bruh, I swear I'm getting dumber everyday day!!!
Answer:
the solutions are 1 and -7
Step-by-step explanation:
first add 14 to both sides
2x²+12x=14
2(x²+6x)=14 now find half of 6x and square it, then add it to both sides
2(x²+6x+9)=14+18(9 was multiplied by 2)
no factor
2(x+3)²=32 divide both sides by 2
(x+3)²=16 square root both sides
x+3=+/- 4 subtract 3
x= 4-3=1
x= -4-3=-7
The number of cards left is 600-280=320.

Answer:
Step-by-step explanation:
hello :
the point-slope formula is :
y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope
in this exercice : x_1 = -1 y_1 = 4 m = 3
so : y - 4 = 3(x +1) ...an equation for this line .
