Answer:
The answer is 27, 53, and 62
Step-by-step explanation:
This is the answer because 27 is the lowest and then 53 and then you have 62 because it is the biggest.
Let the original fraction be
Now let's increase both numerator and denominator by 2:
This produces a 1/12 increase:
The left hand side can be rearranged as
Invert both sides:
Solve the quadratic equation:
So, in the first case, the original fraction is
In the second case, we have
Answer:
x² +4x
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Given: base= 2x, height= x +4
Area of triangle
= ½(2x)(x +4)
= x(x +4)
= x(x) +x(4) <em>(</em><em>expand)</em>
= x² +4x
