Answer:
4
Step-by-step explanation:
The correct option is 4.
Put 4 in the missing term because 4 is a perfect square and it satisfies the given expression:
4x2 + 40x + 100
Now multiply the 1st term coefficient with 100
4 *100 = 400
Now find two numbers whose product is 400 and whose sum is 40
20*20 = 400
20+20 = 40
Therefore 4 is the correct missing coefficient because it satisfies the expression:
Thus the correct option is 4....
Answer:
The answer is AB.
Step-by-step explanation: We are given four blood types and also the number of males and females having each of the blood type. We are to decide the blood type that is independent of the gender.
We can see that the difference between the number of males and females in the blood types A, B and O are large.
Only in the blood type AB, the difference is very small, i.e., the number of males and females having AB blood type is more or less same. So, we can conclude that AB is independent of the gender.
Thus, AB is the correct answer.
B.7y+6
Add 3y and 4y together since it’s both y

Step-by-step explanation:
The Bisector Angle Theorem basically states that if a bisector cuts the middle of an angle, the two angles that it creates will be equal to each other.
Therefore:
#7 -> x=38
#8 -> x=144
#9 -> 2x=84 -> x=42
#10 -> x+3=30 -> x=27
Answer:
2 and 3/8
Step-by-step explanation:
4/6 = 6/8 so 5/8 + 6/8 = 2 and 3/8
