Answer:
I honestly don't know how to solve anything like this but my best guess is 135
Step-by-step explanation:
I used the area of a circle formula to find the area of the two semi-circles, and then added it to the area of the rectangle. (Once again, I really do not know xD)
The right answer is: d.112 + 25m + 45 = 50 + 60m
Step-by-step explanation:
Let m be the number of months
<u>For First Runner:</u>
He already has 112 in savings and got 45 from a friend so these will be constant values and as he will be saving $25 each month so

<u>For Second Runner:</u>
He already has $50 in saving and ill save 60 each month so

In order to find that when there accounts will have same amount, the expressions for both will be put equal

The value of m will give us the number of months after which the accounts of both runners will have same amount.
Hence,
The right answer is: d.112 + 25m + 45 = 50 + 60m

An example for #1 would be that: 15 is divisible by 3, but not 9. every third multiple of 3, (9, 18, 27,...) is divisible by 9 because 9 is three times the size of 3.
For part two the first number that I thought of is 23.
Answer: Domain: (-inf,inf) Range; [-4,inf)
Step-by-step explanation: Domain is x values possible and range is y values possible. Quadratics always have a domain of (-inf,inf) and the range starts from -4 going up infinitely. and if -4 is included then we use a bracket therefore, [-4,inf). Also, infinity always has a parenthesis.
