Does anyone know how to do this
Paraphin [41]

Answer: 7(x+2)(x+3)

Step-by-step explanation:

First, you want to find the GCF, 7 goes into all the terms evenly

so 7x^2 + 35x + 42 = 7(x^2 + 5 + 6)

to factor (x^2+5+6), you want to find two numbers whose product is 6 and whose sum is 5 (2 and 3)

so (x^2 + 5 + 6) becomes (x+2)(x+3)

and 7(x^2 + 5 + 6) becomes 7(x+2)(x+3)

there are 225 wolves in a state park the population is increasing at the rate of 15% per year you want to make a prediction for
erastova [34]
Well, here is how i would do it.

We start with 225, at a rate of 15% per year. Assuming your answers are in years and not months, we will increase by this increment; years.

So, we start with 225, and a 15%, or .15, increase. So what we would do, it take 225 times .15. One way ive learned to do this (via algebra class) is that you can times it by 1.15 to make it quicker, this just takes out the adding step.

So after one year, we would have a total of 258.75, or about 259 wolves.

after two years, we would have about 298 (we cant have a half of a wolf!)

after 3 years, we would have about 343 wolves.

after 4 years, we would have about 394 ish

after 5 years, we would have about 453

after 6 years, we would have about 521.

So, it would take about 5 and a half years, if thats an option choice.

Factor completely and then place the factors in the proper location on the grid. 8 y^2 + 6 y + 1
Firlakuza [10]

Answer:

(4y + 1)(2y + 1) -- Unfortunately I can't help with the grid part

Step-by-step explanation:

Multiply the a and c term (8 * 1) to get 8. Think of what factors of 8 would add up to your b term (6), which would be 4 and 2. Rewrite your equation as 8y^2 + 4y + 2y + 1 and consider one half at a time and factor them individually. For the left, that'd be 4y(2y + 1), and for the right, you can't factor anything so it's just 1(2y + 1). Check that the things inside the parentheses are the same, which they are, and add the things you factored out and multiply that by the part in the parentheses for (4y + 1)(2y + 1).
