Answer: The correct answer would be C. x^2+14x+7

Step-by-step explanation: Since there are no variables or numbers in common to factor all three numbers, then this one cannot be factored out with the GCF also known as the Greatest Common Factor. A, B, and D can be factored, either with the variable x or the number that can go into all three of the numbers for each answer.

A bucket contains 6 green tennis balls, 2 yellow tennis balls, and 7 red tennis balls. Tony removes 3 tennis balls, with replacement, from the bucket.



What is the probability that the first tennis ball is yellow, the second tennis ball is green, and the third tennis ball is red?


Answers:
A. 2/15, 0.40, 0.47

B. 0.40, 7/15, 2/15

C. 0.4, 0.13, 0.47

D. 2/15, 7/15, 0.40

Answers

Answer:

A. 2/15, 0.40, 0.47

Step-by-step explanation:

6 green tennis balls

2 yellow tennis balls

7 red tennis balls

15 total tenis balls

probability that the first tennis is a yellow ball:

[tex]\frac{2}{15}[/tex]

probability that the second tennis ball is green:

[tex]\frac{6}{15} = 0.40[/tex]

probability that the third tennis ball is red:

[tex]\frac{7}{15} = 0.4666 = 0.47[/tex]

I think it’s D because you count the total tennis balls together which gives u a denominator of 15. So it’s 2/15 and 7/15 and 6/15. Since 6/15 is not on option D. I made 6/15 into a decimal which was 0.4 and 0.4 is the same as 0.40. So the answer is D.

the school is planning to add 2 new playgrounds each playground will be the shape of a square that measures 21 m by 21 m what will be the area of the playgrounds

Answers

Answer:

The area of the playgrounds will be 441 sq. M.

Step-by-step explanation: This is because to get the area of a square you multiply base time height or b x h = x. So for this all you need to do is solve 21 x 21, which is 441 sq. M.

(P.s if you need the combined area then the answer is 882 square meters.)
