One plus 1 equal je 2
2xy- 7yz + 5zx + 10xyz Is The Answer I Believe
Answer:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=10·4+6·4+8·4+1
2·﹣104+2·(10·6)2+2·(10·8)2﹣64+2·(6·8)2﹣84=144

The answer to your question is:
Step-by-step explanation:
12.-
x² - 6x = 5
x² - 6x + (3)² = 5 + (3)²
x² - 6x + 9 = 5 + 9
(x - 3)² = 14
13.- x² - 6x = 12
x² - 6x + (3)² = 12 + (3)²
x² - 6x + 9 = 12 + 9
(x - 3)² = 21
x - 3 = ±√21
x1 = √21 + 3 x2 = -√21 + 3
x1 = 7.58 x2 = -1.58
14.- 2x² - 24x = - 20 Divide by 2
x² - 12 x = -10
x² - 12x + (6)² = - 10 + (6)²
x² - 12x + 36 = - 10 + 36
( x - 6) ² = 26
x - 6 = ±√26
x1 = √26 + 6 x2 = -√26 + 6
x1 = 11.1 x2 = 0.9
Answer:
6:9
Step-by-step explanation:
4:6 can be simplified to 2:3
4:16 = 1:4
4:12 =1:3
5:10 = 1:5
6:9= 2:3 --> it would have to be this one
Hope this helps!!!! :)
