Answer 1

Question 5: The missing term her is r²

Question 6: The missing term here is 3.

Explanation:

Question 5:

Let's write the equation and then solve it for the missing term. We will call this term x.

`(6r^(4)+4r)+(x-2r^(4)+3r)=4r^(4)+r^(2)+7r`

First, we simplify the letf term adding the similar terms.

`x+4r^(4)+7r=4r^(4)+r^(2)+7r`

Now, we substract 4r⁴ and 7r in both sides.

`x=r^(2)`

Therefore, the missing term her is r²

Question 6:

Here, we will call the missing term y. Now, let's solve it for y.

`(y-8x-x^(2))-(4x^(2)-7+6x)=-5x^(2)-14x+10`

Let's first distribute the minus sign into the parentehsis.

`y-8x-x^(2)-4x^(2)+7-6x=-5x^(2)-14x+10`

Now simplify the left side by adding similar terms.

`y-14x-5x^(2)+7=-5x^(2)-14x+10`

Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.

`y=10-7`

`y=3`

Therefore, the missing term here is 3.

I hope it helps you!
