Answer: 12/10 and 24/20
Explanation if you simplify these fractions it’s becomes 6/5
The answer is 3 11/12 because the last one said RUNNING and it asked how much did he SWIM. Here is the math.
6/12 + 5/12 = 11/12
1+2=3
3 11/12. Hope this helped!

Determine the domain of the function
To do this, we need to solve for the vertex, p of the function
Given the the general form of a quadratic function is:
By comparison, we have:
So:
Substitute 1 for p in
This implies that
The interpretation of this is that;
<em>For every value of p, there's a corresponding value of R.</em>
<em>However, because p indicates price and it's impossible to have a negative price, we can say that the minimum value of p is 0;</em>
Hence, the domain is
Answer:
A
Step-by-step explanation:
Let the smaller room have an area of x^2
Let the larger room have an area of (x + 3)^2
(x+3) ^2 + x^2 = 89 Be careful not to make it 89^2.
x^2 + 6x + 9 + x^2 = 89 Expand the binomial squared
2x^2 + 6x + 9 - 89 = 0 Subtract 89 from both sides
2x^2 + 6x + 9 - 89 = 0 Combine
2x^2 + 6x - 90=0 Divide by 2
x^2 + 3x - 45 = 0 This factors.
(x + 9)(x- 5) = 0
X + 9 gives nothing useful
x - 5 = 0
x = 5
x + 3 = 5+3 = 8
So the answer is A
