Step-by-step explanation:
Any answer that involes,
Step 1: Complete the Square



Step 2: Turn the left side into a binomial

Step 3: Solve for x.



OR


X=-3 or X=13
Because, well, without them how are you able to add and subtract fractions :D
It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
Y = 5(3x)....y = total number of bowls and x = number of weeks
for 4 weeks......x = 4
y = 5(3*4)
y = 5(12)
y = 60...so the family will eat 60 bowls in 4 weeks
The line GH bisects The triangle FGI meaning it divides it into two equal parts <em>(that is the definition if bisection); </em>therefore, the angles FGH and HGI are equal:

Now let us add 2 to both sides gives

subtracting 4x from both sides gives


Hence, x = 11.
The measure of FGH is

(B)
The measure of HGI is

(C)
The measure of FGI is the sum of HGI and FGH:
