81a²-25 would be the answer I'm pretty sure. Hopefully I helped.
Answer:
It would be a negative or positive depending on the situation.
Step-by-step explanation:
A negative minus a negative would result in either a positive or negative. For example, -8 - (-9) would be 1 while -8 - (-7) would be -1. If the negative number your subtracting is greater than the number you're subtracting from then it will be positive, vice versa.
Answer: 6,160,000 db
Step-by-step explanation:
The sound of a jet engine is 70,000 times louder than that of a lawn mower.
Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:
= Sound of lawnmower * 70,000
= 88 * 70,000
= 6,160,000 db
Answer:
=x^2+7x+10
Step-by-step explanation:
Simplify: xx+5x+2x+2.5: x+7x+10
Add similar elements: 5x+2x= 7x
=xx+7x+2.5
xx=x2
2.5=10
=x+7x+10
Answer: =x^2+7x+10
