I don't know the answer but try using PEMDAS. (Parentheses, Exponents, Multiplication, Division, Addition, and then Subtraction)
Answer: 15:13
Step-by-step explanation: 7/7=3500
<h2>
1/7=3500÷7=500</h2><h2>
500x3=1500</h2><h2>
1500+700=2200</h2><h2>3500-2200=1300</h2><h2>1500:1300</h2><h2>15 : 13 (if there is a need to simplify the ratio)</h2><h2 />

Step-by-step explanation:
Solve for hypotenuse.
Answer:
The answer is B
Step-by-step explanation:
Its just B
(x-y)(x^2+xy+y^2)
The first parentheses contain the cubed root of both the terms so x and y respectively. second parentheses follows the formula (a^2 + ab + b^2)
x corresponds to a and y corresponds to b. The signs are what change depending on what the original equation is. Since the original is a subtraction then the signs are -/+/+. you can remember it using the acronym SOAP. (S = same, O = opposite, AP = always positive) So the first sign is x - y (same as subtraction from original), the second and third are x^2 + xy + y^2 (opposite is a plus, and the last sign is always a positive.
