Answer:
24
Step-by-step explanation:
Find the number that 9 multiplies by to get 54
so
9x6=54
do the same to four
4x6=24
Or
cross multiply
Lets put N as the missing number
4x54=9xN
Solve
216=9N
24=N
3x^2-6x+5
for ax^2+bx+c=0
discriminant is b^2-4ac
when
1. b^2-4ac>0, there are 2 real roots
2. b^2-4ac=0, there is 1 real root
3. b^2-4ac<0, there are 2 complex roots
3x^2-6x+5
a=3
b=-6
c=5
(-6)^2-4(3)(5)
36-60
-24
answer is -24 is the discriminant
Answer:
C = -13.78
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
If this figure is a rhombus, then the two sides have to be equal:
3x+9=8x-1
Move like terms to one side (note that when you move it, the sign flips. Ex: - becomes +)
3x-8x=-9-1
-5x=-10
Divide both sides by -5
x=2
