Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.
All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
If the diameter is 16, then the radius is 8.
Your equation is:
(x - 7)² + (y + 5)² = 64
Answer:
x = 24
Step-by-step explanation:
10:8
10(3) = x(3)
x = 8
30 : 24
= <span>(-8x - 9)(-9x2 + 7x - 9)
= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81
= 72x³ + 25x² + 9x + 81
In short, Your Answer would be: Option D
Hope this helps!
Answer:
9 minutes
Step-by-step explanation:
60=15+5t
45=5t : subtract 15 from both sides
