Answer:
Only equation 1 and 2 are equal.
Step-by-step explanation:
2 (x + 4)2 = 2
2( x² + 8x+ 16) = 2 Applying the square formula
2x² + 16x+ 32 = 2
2x² + 16x+ 32 -2= 0
2x² + 16x+ 30 = 0
2( x² + 8x+ 15)= 0 Taking 2 as common
x2 + 8x + 15 = 0------------eq 1
x2 + 8x + 15 = 0-------------eq 2
(x − 5)2 = 1
x²-10x+25= 1 Applying the square formula
x²-10x+25- 1= 0
x²-10x+24= 0-------------eq 3
x2 − 10x + 26 = 0 -------------eq 4
3(x − 1)2 + 5 = 0
3( x²-2x+1)+5= 0 Applying the square formula
3x²-6x+3+5= 0
3x²-6x+ 8= 0-------------eq 5
3x2 − 6x + 8 =1
3x2 − 6x + 8 -1=0
3x2 − 6x + 7 =0-------------eq 6
Answer: 21.13 miles

Answer:
£ 38,110
Step-by-step explanation:
We need to find salary for 1 year (12 months).
- Monthly Salary = 1410, so yearly would be:
1410 * 12 = 16,920
- 26% of total profit. Let's find the profit first:
Profit is Income - Cost
So, that would be (from table):
Profit = 549000 - 473500 = 75,500
26% of that would be:
26/100 = 0.26
0.26 * 75,500 = 19,630
- 390 bonus for each month she sells atleast 16 cars
Out of 12 months (1 year), she sold at least 16 cars in 4 months, so she gets bonus of 390 for those 4 months, that would make:
390 * 4 = 1560
Total Pay for the year would be summation of all these:
Total Pay = 16,920 + 19,630 + 1560 = £ 38,110
Answer: 31.80
Step-by-step explanation:
First you divide 26.50 by 0.20 to get 5.3 then you add that to the starting total and you get your answer which is
