Answer: 63
Explanation: trial and error of comparing
(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
Answer:
(x+6)² + (y-6)² = 181
Step-by-step explanation:
equation of the circle in general is (x - a)² + (y - b)² = r²
center is (a, b) in our task a=-6 b=6
so equation of the circle is (x+6)² + (y-6)² = r²
we have point (3,-4) ⇒ x=3 y=-4
put x y in equation of the circle ⇒ (3+6)² + (-4-6)² = r² ⇒r² =181
⇒The equation of a circle is (x+6)² + (y-6)² = 181
