Answer:
x = 86
Step-by-step explanation:
The average of a set of data is equal to the sum of the numbers divided by
number of the sample . In our case we have
98 , 99 , 86 , 89 , 70 and x the uknown, and we know that the average need to be 88 so
(98+99+86+89+70+x ) / 6 = 88
442 + x = 528
x = 528 - 442
x = 86
The answer is C because a negative divided by positive is a negative
The answer is 29.
I hope it helps if not pls let me know
X^2-3x-10. You solve it by foiling. I attached a photo explaining how to do it.
Answer:
2 x 2 x 2 x 3
Step-by-step explanation:
Find two numbers that multiply together to form 24:
2 x 12 = 24
Find two numbers that multiply together to form 12, a factor of 24. Replace 12 with these numbers:
2 x (2 x 6) = 2 x 12 = 24
Find two numbers that multiply together to form 6, a factor of 12. Replace 6 with these numbers:
2 x (2 x (2 x 3)) = 2 x (2x6) = 2 x 12 = 24
Two and three cannot be factored any further, therefore the prime factors of 24 are 2, 2, 2, and 3.
