7/9
This is because, in this scenario, a 100% probability is 9/9 and if the probability he will win is 2/9, then the probability he will lose is 9/9-2/9=7/9
Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)
Answer:
1. given
2. distributive property
3. addition property of equality
4. commutative property
2+20t-5t^2=12
5t^2-20t+10=0
t^2-4t+2=0 complete the square
t^2-4t=-2
t^2-4t+4=2
(t-2)^2=2
t-2=±
t=2±
t≈(0.586, 3.41)
No need for pie here!
8x4=32
(3x3)/2=4.5
(3x2)/2=3
32+4.5+3= 39.5
