Answer:
4x² + 9y² + 12x - 18y - 12xy + 9
Step-by-step explanation:
Given
(2x - 3y + 3)² = (2x - 3y + 3)(2x - 3y + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x - 3y + 3) - 3y(2x - 3y + 3) + 3(2x - 3y + 3)
Distribute the 3 parenthesis
= 4x² - 6xy + 6x - 6xy + 9y² - 9y + 6x - 9y + 9 ← collect like terms
= 4x² + 9y² + 12x - 18y - 12xy + 9
Answer:
1. x >= 5
2. x > -8
3. x < 4
4. x <= 8
Step-by-step explanation:
AC and AB are tangents to circle O, meaning that the angles C and B are right angles of 90 degrees. Since a quadrilateral's internal angles must sum up to 360 degrees, this means that A + B + C + O = 360
70 + 90 + 90 + O = 360
O = 110 degrees.
Hi!
The expression would be or be similar to 10 x 4 + 8
Hope this helps !
Its c because yea it just is udk how to explain it
