B)40 because (4)*50/5 is (4)*10
Answer:
3(a +3)
Step-by-step explanation:
(a+3)^2 -a(a+3)
FOIL
a^2 +3a+3a+9 -a(a+3)
Distribute
a^2 +3a +3a +9 -a^2 -3a
Combine like terms
3a +9
FACTOR out a+3
(a+3)( a+3 -a)
(a+3) (3)
3(a+3)
Answer: #64, A. #67, A. #68, C
Step-by-step explanation:
#64
0.96/6= 0.16
2.4/16= 0.15
32= 0.18
16 oz is the least
#67
100/20=5
3*5=15
SO, it's 15%.
#68
Divide
$430/43= $10
$594/54= $11
Andrew= $8
So, Darren makes the most.
Answer:
5 mins difference
Step-by-step explanation:
1 3/4 hours = 1 hour and 45mins
50-45=5mins
1) 78.5/pi = 25
radius = 5
The one 5 digits away from that coordinate is (2,-1)
2) This question is area, not perimeter. The width and length has to be added by 4 because of 2 feet on both sides.
9*10 = 90 - 30 = 60
3) 25pi according to pythagorean theorem.
