2/3=3/2? No
3/5=12/20? Lets try and see
If we <span>simplify 12/20 what do we do? Well we take 4*3=12 and 4*5=20
Now that we simply the 4 from both the numerator and denominator we get our answer 3/5
Your answer will be B.</span>
Answer: Exactly square root 58 inches
Step-by-step explanation: The dimensions given for the right angled triangle are 7 inches and 3 inches respectively. The third side is yet unknown. However what we know is that a right angled triangle can be solved by using the Pythagoras theorem which states that,
AC^2 = AB^2 + BC^2
Where AC is the longest side. The question requires us to calculate the longest side and with the other two sides already known, the Pythagoras theorem now becomes,
AC^2 = 7^2 + 3^2
AC^2 = 49 + 9
AC^2 = 58
Add the square root sign to both sides of the equation
AC = square root 58 inches
