The Distributive property states that when we have the statement a(b + c), we can "distribute" the a by multiplying a times both terms that are inside the parenthses.
So in this problem, 2(5 + 7) can be simplified by distributing the
2 through both terms that are inside the set of parenthses.
So we have (2 · 5) + (2 · 7).
Answer:
By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.
Answer:
9 to 4
Step-by-step explanation:
If you divide each of the first numbers on the answers by each of the second numbers they all become a ratio of 2 to 1 except for 9 to 4.
Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
