Answer:
10x² + 3xy + 3x - y² + 3y
Step-by-step explanation:
(2x + y)(5x - y + 3)
10x² - 2xy + 6x + 5xy -y² + 3y
10x² + 3xy + 3x - y² + 3y
Answer:
An angle measures 130° more than the measure of its supplementary angle.
Therefore the required angle is (180°-130°)°=50°
<h3>50° is the right answer.</h3>
Answer:
⏩12°
Step-by-step explanation:
4x + 7° + 35° = 90° {being complementary angles }
4x + 42° = 90°
4x = 90° - 42°
4x = 48°
x = 48° / 4
x = 12°
