Answer:
That can be re-written:
x^2 + 5x -8 = 0
We use the Quadratic Formula
a=1
b = 5
c = -8
x = [-b +- sq root (b^2 - 4ac) ] / 2a
x = [-5 +- sq root (25 - - 32)] / 2
x1 = [-5 + sq root (57)] / 2
x1 = 1.27491722
x2 = [-5 - sq root (57)] / 2
x2 = -6.2749172176
Step-by-step explanation:
➡3x - ( 7 over 12)
➡ [12 (3x ) - 7 ] over 12
➡ ( 36x - 7 ) over 12
I think the answer is: -4.25
Answer:
b = 12.5
Step-by-step explanation:
2=3.5(-3)+b
2=-10.5+b (you add 10.5 on both sides)
b= 12.5
1.36*10^7
where the 36 repeats so 36363636363636... and so on
