Answer:
search up-area of circle formula and circumference of a circle formula
Step-by-step explanation:
x2 - 12x - 12 = 0
(x - 6)2 - 48 = 0
(x - 6)2 = 48
Hence, the answer is (B).
Answer:A)0.27
B)0.78
Step-by-step explanation:
This is the probability of picking 2balls of same color.
P(RR)+Pr(WW)+Pr(BB)
3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=
24/90=4/15=0.27
B)if the first ball is not returned, then there are 9 balls left.
Then probability of same color will be
PrB+PrW+PrR
2/9+3/9+2/9=
7/9=0.78
Answer:
-2x-2
Step-by-step explanation:
this is the right answer
Answer:
jk(x) = -16x^2 -12x+10
Step-by-step explanation:
j(x) = -4x+2
k(x) = 5+4x
jk(x) = (-4x+2) (5+4x)
FOIL
-4x*5 +-4x*4x +2*5 +2*4x
Combine like terms
-20x-16x^2 +10+8x
-16x^2 -12x+10
jk(x) = -16x^2 -12x+10
