Answer:
2500
so first you have to 100x 10 then times 2.5
Step-by-step explanation:
Hi there!
I'm going to assume you mean m^2 + m - 20.
The factor of this is (m + 5)(m - 4)
And I found this by finding what two numbers add to 1 and multiply to -20, which is 5 and -4.
Now if you FOIL this, (First, outer, inner, last terms) you should come to the initial equation.
(m + 5) * (m-4)
m * m = m^2
5 * m = 5m
m * -4 = -4m
5 * -4 = -20
So, in combining like terms, you'd get m^2 + 1m -20.

Answer:
A) similar; SSS similarity
Step-by-step explanation:
You have to find the proportion by dividing each side to the according side
35/14 = 2.5 - S/D
20/8 = 2.5 - R/E
30/12 = 2.5 - Q/F
STEP 1:
find the difference between the total miles of the trip (762 miles) and the miles already traveled (510 miles)
= 762 - 510
= 252 miles left of trip
STEP 2:
divide miles left from step 1 by 3 days
= 252 ÷ 3 days
= 84 miles per day
ANSWER: She needs to travel 84 miles each of the 3 days to complete the trip.
Hope this helps! :)
