I hope this helps you
x^2+x-6 = (x+3)(x-2)
x => +3
x => -2
x^2-2x-15= (x-5)(x+3)
x => -5
x => +3
(x+3)(x-2)/(x-5)(x+3)
x-2/x-5
Use cosine rule and sine rule
You can write it by putting 55 over 100 and simplify then you get an answer of 11 over 20.
Answer:
Step-by-step explanation:
Use proportions to solve.
Corresponding sides have same ratio.
<u>Question 1</u>
- (6x + 3)/17 = (8x - 1)/21
- 21(6x + 3) = 17(8x - 1)
- 126x + 63 = 136x - 17
- 10x = 80
- x = 8
<u>Question 2</u>
- (x + 8)/21 = 32/28
- x + 8 = 21*8/7
- x + 8 = 24
- x = 24 - 8
- x = 16
