Combine the radicals 4V7 +3V28​
Yanka [14]

Answer:

The answer is

<h2>10 \sqrt{7}</h2>

Step-by-step explanation:

To solve the radicals make sure that they both have the same radical

That's

<h3>4 \sqrt{7}  + 3 \sqrt{28}</h3>

Simplify 3√28 in order to combine the radicals

We have

<h3>3 \sqrt{4 \times 7}  = 3 \times  \sqrt{4}  \times  \sqrt{7}</h3><h3>= 3 \times 2 \times  \sqrt{7}</h3><h3>= 6 \sqrt{7}</h3>

So we now have

<h3>4 \sqrt{7}  + 6 \sqrt{7}</h3>

Using the rules of surds

That's

<h3>x \sqrt{a }  + y \sqrt{a}  = (x + y) \sqrt{a}</h3>

Simplify the expression

We have

<h3>4 \sqrt{7}  + 6 \sqrt{7 }  = (4 + 6) \sqrt{7}</h3>

We have the final answer as

<h3>10 \sqrt{7}</h3>

Hope this helps you

Can someone please explain how to do this problem for me?
ololo11 [35]

Answer:

We always start with the x because in the alaphbet x is before y. So it says x=1 and the graph is skipping by 2 so in the middle of where the interact and beside positive 2 on the x row is where the 1 is so you keep it there for now. Now for the y you can see the middle where the interact well that is 0 so you have to keep the dot on the x place because if it said y=2 we would move it but is says 0 so we dont move it!
