Answer:

(3x+2)(x+4)

Step-by-step explanation:

(3x+2)(x+4) = (3x)(x) + (3x)(4) + (2)(x) + (2)(4)

= 3x² + 12x + 2x + 8 *****

= 3x² + 14x + 8

You start by figuring it will be in the form of (3x + a)(x + b) because 3 doesn't factor. The two middle terms in the line followed by the stars must add up to 14x. And in (3x + a)(x + b), ab must be equal to the 8 on the end (the constant factor).

For most people, factoring takes a LOT of practice. And somethimes you just have to try a lot of factors before you hit the right combination. But if you do it enough, it really does get easier to 'see' the answer a lot of the time.

Hope this helped!

Plz help with this question ASAP which choice is it and steps to get the answer or explain why
Savatey [412]

Answer:

D 20 *1.10 * 1.05

Step-by-step explanation:

We have 19.8 tons of wheat.  That is close to 20 tons

We increase by  9.8 percent. 9.8% is close to 10%

When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%.  In decimal form that is 1.1

20 *1.10

Then the next year we increase by 5.1%.  That is close to 5%

We have 100% plus the 5% or 105%, which in decimal form is 1.05

We multiply what we had (20 *1.10) by 1.05

20 *1.10 * 1.05

This is the total amount we have

Andru [333]

Answer: I believe it is A

Step-by-step explanation:

In this table, you have to look at multiple things in the table. So you have to look at where it says Under 40 <em>and</em> that don't read the paper. So according to what I learned with this, you would have to do 36/40 and then get 0.9 which would be in percent form: 90 %.

I would recommend looking at another person's response also, before you submit this question. But hope this helps!
