(6×5) + (6×2) = 6×7
It works if you think about it like this:
5 sixes + 2 sixes = (5 + 2) sixes = 7 sixes
This is an example of the <em>distributive property</em>.
To put it simply, we're applying the same multiplication (×6) to two different things which are being added together (5+2).
Here's another example of the distributive property:
2×(3+4) = 2×3 + 2×4
30 times 35 is 1050 so 1050/30=35
Answer:
33.8
Step-by-step explanation:
1) Use Phythagoras theorem to get RS ↓

2) RS = RQ
therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

Hope this helps =)
