Answer:
26 socks
Step-by-step explanation:
There are a total of 48 socks here. Let us assume you pulled out 24 socks at a go and all are red. Now, you would have exhausted the number of red socks here. You would be left with only blue socks which you can pull one after the other to give a total of 26 socks pulled out to have 2 blue socks at least.
Answer:
(5a-2)(5a-2) or (5a-2)^2
Step-by-step explanation:
25a^2-20a+4
factor out the trinomial,
(5a-2)(5a-2)
Find two numbers that when they multiply, you get the third term, which is 4 in this case. And when they add up, you get the second term, which is -20 in this case.
Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
Answer:
Compass bearings use the four directions on a compass in order to find the direction of one object from another. An example is N20°E. True bearings use the number of degrees measured clockwise from north an object is. An Example is 120°T.
