3p4(4p4)+3p4(7p3)+3p4(4p)+3p4(1) seperate then multiply make sure to apply exponent rules.
12p8+21p7+12p5+3p4 is your anwser.
Answer:
12 seconds
Step-by-step explanation:
Let's take 6, 12 as our first example. We're trying to find out the difference between the two...take 12 minus 6 and you get a difference of 6 between them.
Now the first problem, 4, -17...put the larger one first and subtract the smaller one. 4 minus negative 17 is the same as 4 plus 17 which is 21.
23-8 is 15, of course.
-1-14 is -15, but the difference between something can't be negative, so it's just 15.
18-(-3) = 18+3 = 21.
Answer:
Sam is yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister
Step-by-step explanation:
The relationship between the ages of the brothers are;
Sam's age + Dean's age = Their sister's age
Dean's age + 10 = Dean's age + Sam's age
Therefore, we have;
Sam's age = Dean's age + 10 - Dean's age = 10
Sam's age = 10 years
Let 'x' represent their sisters age, we get;
Sam's age + Dean's age = x
10 + Dean's age = x
Dean's age (in variable form) = x - 10
Answer:It's an arithmetic sequence with a common difference, d, = 4
A1 = 8
A2 = 8+4 = 12
A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8
AN = A1 + d(N-1)
AN = 8 +4(N-1) = the Nth term in the sequence
