102 multiply 5 is equally to 610 so that's gonna be 6.10 I think
3x^2+11x-4=10x-1
3x^2+11x-10x-4+1=0
3x^2+x-3=0
Δ=1^1-4*3*(-3)=1+36=37
x1=(-1+V37)/6
x2=( -1-V37)/6
Answer:
r = 2
Step-by-step explanation:
2(8r + 5) = 24 + 9r
16r + 10 = 24 + 9r
16r - 9r = 24 - 10
7r = 14
r = 2
Answer:
8
Step-by-step explanation:
Because 16 is the diameter and to find the radius you need to divide by 2
(9/6) = (15/?)
9? = 90
? = 10
