In order to solve this, we can multiply out the answer choices and check if they are correct by using FOIL. A would be x^2 + 7x + 12. B would be x^2 - 7x + 12. C would be x^2 - 7x + 10. D would be x^2 + 7x + 10. The answer choice that matches the question is C. (x - 2)(x - 5).

Hope this helps!

A certain species of bird is in danger of becoming extinct. There were 1500 birds in 2000 and they are
melamori03 [73]

a) If this trend continues, how many birds will be left by 2010 will be 525

b) The  birds would there have been in 1990 will be 2475

<h3>What is rate of increase?</h3>

Rate of increase or decrease is defined as the increment or decrement in any quantity over a period of time constantly.

Here we have the data that:

There were 1500 birds in 2000 and they are decreasing at an annual rate of 6.5%.

a) If this trend continues, how many birds will be left by 2010

{1500x6.25}/{100}=97.5

So the bird decrement in the one year will be =97.5 so it will be in the 10 years or upto 2010 will be

97.5x10=975

So the birds left till 2010 will be:

Q=1500-975=525

b)The birds would there have been in 1990 will be:-

=1500+975=2475

Hence If this trend continues, how many birds will be left by 2010 will be 525.The  birds would there have been in 1990 will be 2475

Factor each expression by factoring out the common binomial <br><br> 5a(y + 4) + 8(y + 4)
Tems11 [23]

Answer:

Factoring the term 5a(y + 4) + 8(y + 4) we get (y+4)(5a+8)

Step-by-step explanation:

We need to factor the term: 5a(y + 4) + 8(y + 4)

Factoring:

5a(y + 4) + 8(y + 4)

Taking (y+4) common

(y+4)(5a+8)

It cannot be further factored.

So, Factoring the term 5a(y + 4) + 8(y + 4) we get (y+4)(5a+8)
