Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
Yes, because adding 50 and subtracting 50 is equal to 140+50-50.
+50-50=0
Now, you have 140+0=140.
Hope this helped☺☺
Step-by-step explanation:
Angle at Center = 2 * Angle at Circumference
Therefore B = 2A.
When B = 100°, A = 100°/2 = 50° (B),
When A = 48°, B = 2(48°) = 96°. (C)
Answer:
Step-by-step explanation:
3 - 13x - 7x^2 - (5x^2 + 12x - 10) =
3 - 13x - 7x^2 - 5x^2 - 12x + 10 =
- 12x^2 - 25x + 13 <===
