You're not adding them, you're multiplying them. There's a multiplication sign in what I wrote.
(6 plus 2) TIMES (4 plus 2) = 48.

You're just finding the area of the new rectangle.
Draw a picture.
First you have a 6cm x 4cm rectangle.
Add 2cm to each side and you have a 8cm x 6cm rectangle.
Work out the area for both.
Sorry, I don't know how to explain it simpler...

I've been looking at this question for about 30 minutes and i can't do it

A number pattern follows the rule n^2+3n+2: that is, the number pattern is 6,12,20… found by substituting n=1, n=2, n=3 into the rule.

a.)  Find the next value by substituting n=4 into the rule

I first checked how they got 6, so i put n=1 into 3n which is 3 times 1 so it says the same, i then used the null factor law using cts as inspection didn't work and i didn't get 6?

Why are you using Null factor Law and CTS and stuff? It's not necessary to the question as the statement does not equal zero....
Just substitute n=4 into the formula.

then how do you find n?

then how do you find n?

They tell you to sub N=4 into the formula to find the next value.
So you do 4^2+3(4)+2 which equals 30; so the next value is 30.

Multiply both sides by 6.
3(4y - 5) - (2y - 1) = 6y

Expand.
12y - 15 - 2y + 1 = 6y

Collect like terms.
10y - 14= 6y

Take away 6y from both sides.
4y - 14 = 0

Add 14 to both sides.
4y = 14

Divide both sides by 4.
y = 14/4
= 7/2
= 3.5

Cheerss

It's alright, I got it wrong too :)
Mistakes don't really mean anything as long as you learn from them.

For me, I got it wrong because I wasn't paying much attention to how both sides of the equation have to be multiplied together.

It's important that your realise where you went wrong :)

After all, making mistakes here doesn't matter, as long as you don't do it on the 3/4 exam xD hehe
