Answer:
7
Step-by-step explanation:
use distributive property first
2x-4=10
then, add positive 4 to -4 and 10 because opposite signs cancel out
2x=14 then we divide
Answer:
3 || 3
6 || 9
9 || 15
12 || 21
In the first column, we see the numbers increasing by +3, serially.
In the second column, we see the numbers increasing by +6, serially.
Answer:
The answer is -2
Step-by-step explanation:
-6 means you go on the left and then you subtract -2 which means go backward 2 Soooo you got the right answer.
Answer:
Yes, \sqrt{2}(\sqrt{3.5} + 2\sqrt{5} )
Step-by-step explanation:
By roots property, the roots can be re-write as multiplications or division, like this:
![\sqrt[n]{a} . \sqrt[n]{b} =\sqrt[n]{ab}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20.%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%5Csqrt%5Bn%5D%7Bab%7D)
Here, we can re-write both roots:
and 
Now we have:
And we can take out the common expression:
⇒ Answer
3+2•6/3
first you multiply the 2 and 6 on the top to get 12
so now it’s
3+12/3
now add the 12 and 3
15/3
now divide
so your answer is 5
