Answer: A

Explanation: The zeroes of f(x) are the value/s of x such that f(x) = 0. So, we need to find the values of x in the equation f(x) = 0.

Note that

f(x) = 0
⇔ x² + 3x - 10 = 0

By factoring into binomials, x² + 3x - 10 = (x + 5)(x - 2). Thus, 

x² + 3x - 10 = 0
⇔ (x + 5)(x - 2) = 0
⇔ x + 5 = 0 or x - 2 = 0
⇔ x = -5 or x = 2

Hence, the zeroes of x are  -5 and 2.

Ack's mother gave him 50 chocolates to give to his friends at his birthday party. he gave 3 chocolates to each of his friends an
wariber [46]
16 because 48/3 = 16 and we know that he started with 50 chocolates then distributed 3 times the number of friends present. This is written as 50 - 3x. We also know that there were 2 chocolates left so -3x = 2 - 50 which when simplified is x = 48/3 which equals 16.

Don has 6 pieces of pipe. Each piece is 2 feet 6 inches long.
Alex777 [14]

Answer: 15 feet

Step-by-step explanation:

First you start with 2ft and 6in and convert it all into into inches.

If you know that 1 ft=12in then you know that 2 feet is the same as saying

12+12=24. If you don't understand use this chart-

1 ft=12in

2ft= 24in

3ft= 36in

4ft =48in

5ft= 60in

6ft= 72in

see I am counting by 12's.

Now take 2ft and convert it into inches. That would be 24 in (look in the chart).

now take the 24in(2ft) and add it to the 6in. So 24+6 =30

So now you know that one piece of pipe is 30in long.

But in the text it states that Don has 6 pieces, so...

because it says that he has 6 pieces of pipe then you are going to take that and multiply that number(6) by how long each piece is. look up and it shows how long each pieces is. They are all each 30in long. Take 30 and multiply that by 6 because there are 6 pipes and you will get 120in.

But it says that they need an answer of feet and inches or just feet if it exactly a some sort of foot like 43feet or 2 feet.  

So then we are going to convert 180 into feet by dividing 180 by 12 and you get 15. So the answer is 15.

I hope this helps. Have fun learning!!
