Answer:
8x^2+19x
Step-by-step explanation:
Simplify the expression by combining like terms. Terms which look a like and sound a like should be added together.
3x^2+7x+3+5x^2+12x
x^2 terms: 3x^2+5x^2=8x^2
x terms: 7x+12x=19x
constants: 3
Together is is 8x^2+19x+3.

Step-by-step explanation:
There’s this app called Socratic that you can use. It’s like this one but it’s a little different
Ok first you have to convert 100 miles to feet.
A mile is 5,280 feet
100x5,280
528,000
Thats how much feet per hour. Now we need to find feet per second. So lets divide 528,000 by 60
528,000/60
8,800
Now we know 8,800 is how much feet per minute now we divide it once more by 60 to find feet per second.
8,800/60
146 2/3
So your answer is 146 2/3ft/sec
