The percent error is 25 %
<em><u>Solution:</u></em>
Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40
<em><u>To find: percent error</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
<em><u>The formula for percent error is given as:</u></em>
Here, exact value = 40 and approximate value or estimated value = 50
Substituting the values in above formula,
Thus the percent error is 25 %

Factor out a 3x:
3x(x2+4x+6)
Since you can't factor out the quadratic that's as far as it goes:
Answer:
3x(x2+4x+6)
The best answer is D.
According to the pythagorean theorem, a^2+b^2=c^2 in a right triangle where a and b are the legs and c is the hypotenuse.
The diagram given gives the length of both legs, so plug it into the equation to get c^2= 24^2+45^2
