Answer: 9−27
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
11x+13=90
11x=77
x=7
49-9=40
72,491 + 19,326 = 91,817
Leah scored 91,817 points
X3-7x=6x-12
x3-7x-6x+12=0
x3-13x+12=0
(x-1)(x2+x-12)=0
Calculate delta of the second bracket:
delta = 1+4*12=49
sqrt(delta)=sqrt(49)=7
x_1=(-1-7)/2=-4
x_2=(-1+7)/2=3
(x-1)(x+4)(x-3)=0
Answear:
Roots: x=1, x=-4, x=3.
