Answer:
The square of this expression is written as ( a − b ) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways. The square of difference of the terms formula.
Step-by-step explanation:
2 . A
because acute angle is less then 90 degrees, and 90 degrees is a right angle, and anything above 90 degrees is obtuse .
Answer:
Step-by-step explanation:
Red = 4
Blue = 6
Yellow = 2
Total = 4 + 6 + 2 = 12
Probability is that event divided by total event, so
Probability of Blue = 6/12 = 1/2
Since, we put the blue again back into the bag, so we still have same amount of each (this is with replacement, probability).
So, 2nd time:
Probability of Blue = 1/2 (same)
Now, we need to multiply these to get probability of blue IN A ROW:
1/2 * 1/2 = 1/4
Answer:
52
Step-by-step explanation:
14+13= 27+2=29+23=52
