Answer:
Step-by-step explanation:
a = 18.2
From sine rule we have
.
Answer:
the answer is :)
Step-by-step explanation:
(x+9)(x+8) = x^2 +17x + 72
(x- 7)(x+8) = x^2 + x - 72
(x- 5)(x- 6) = x^2 -11x + 30
(2x + 3)(3x+2) = 6x^2 + 13x +6
(5x - 4)(2x-5) = 10x^2 - 33x + 20
(x-4)^2 = x^2 -8x + 16
(2x+1)^2 = 4x^2 +4x + 1
(4x+3)(4x-3) = 16x^2 - 9
Find two factors of the last number that add up to the middle number.
a) two factors of 16 that add to 10: 8 and 2. Because 8x2=16 and 8+2=10. then do this:
(x+8)(x+2)
b) (x+4)(x+3)
c) (x+12)(x+1)
