Answer:
<h2>w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)²</h2>
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
We have
w² - 2w = w² - 2(w)(1)
We must add 1²
w² - 2(w)(1) + 1² = (w - 1)²
Answer:
15.6
Step-by-step explanation:
the angle = 180-61-42=77°
x = 14.sin 77/sin 61
= 14×0.97/0.87
= 15.6
42/100 of X = 63 is the equation. Therefore solving this gives you 150 dancers in total. Hope this helps.
2 ones 3 tenths.......So 2.3
Answer:
18
Step-by-step explanation:
Supplementary angles means sum of angles is 180.
4x + 4 + 6x - 4 = 180
4x + 6x + 4 - 4 = 180
10x = 180
x = 180 / 10
x = 18
