Answer:
Step-by-step explanation:
10.
- x + 57 = 116
- x = 116 - 57
- x = 59
11.
- y = 180 - 112 = 68
- x= 180 - 2*68 = 44
12.
- 4x + 10 = 180 - 2*40
- 4x + 10 = 100
- 4x = 90
- x = 90/4
- x = 22.5

Answer:
Step-by-step explanation:
Factor out 6
I assume you mean 6x^2+30x+36, because that makes far more sense
6(x^2+5x+6) = 6(x^2 + 2x +3x +6)
(To find that it is 2x and 3x: 2 +3 = 5, 2 * 3 = 6)
Factor by grouping:
6* x(x+2) +3(x+2) = 6(x+3)(x+2)
For binomials, it could be either (6x+18) (x+2) or (x+3) (6x+12), depending on where you multiply the 6.
Answer:
40,000
Step-by-step explanation:
Given that:
Percentage Cost price of jewelry = 100%
Jewelery was sold at loss of 5% = (100%- 5%) = 95%
If sold at 5200 more ; profit made = 8%
That is ; (100% + 8%) = 108%
Difference between loss percentage and profit percentage = change in price sold
(108% - 95%) = 5200
13% = 5200
If ;
0.13 = 5200
The percentage cost price = 100% will be;
0.13 = 5200
1 = x
0.13x = 5200
x = 5200 / 0.13
x = 40,000
