Answer:
12) 26x^2+22x+25
13) -15x^2-21x-11
14) x^2+32x+18
15) 9x^6+10x^5-15x^4+14
Step-by-step explanation:
When given the scale factor, just multiply!
8cm * 2.5 = 20cm per side
X is pretzels and y is hot dogs
3x + 2y=195
x +15 =y
3x + 2(x+15)=195
5x=165
x=33
D
Step-by-step explanation:
6x + 120y + 6x2
Final answer
If you would like to match each time with a time above, you can do this using the following steps:
a 3h 18m 7s = 11887s<span>
3h = 3 * 60m = 180m; 180m + 18m = 198m; 198m = 198 * 60s = </span>11880s; 11880s + 7s = 11887s
b <span> 8300min = approximately 5 days 18 hours
8300min = 8300 * 60s = </span>498000s
8300 min / 60 min = 138h 20min; 138h / 24h = 5 days 18 hours 20min
c 1461 days
1461 days = 1461 * 24 hours = 35064 hours
d <span>44640min. = 31 days
</span><span>44640min / 60min = 744 hours; 744 hours / 24 hours = 31 days
e </span><span>10:21:2.5
</span>10:21:2.5 = 10 hours, 21 minutes, 2 seconds, 50 milliseconds<span>
</span>
