You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
3 times a year for 2 years is equal to 3 x 2, or 6. So we know that she will have to pay her bill 6 times.
The cost for each trimester is $1450, but we still have to add the book costs ($350). So, 1450 + 350 = 1800.
Now we know that she has to pay $1800 six times. So the equation will be:
1800 x 6 = 10800.
It will cost Samantha $10,800 to get her degree.
Divide 3 apples by $2.50 to get the unit price, $1.20 (The constant of proportionality)
Then multiply 12 apples by the constant ($1.20)
Your final answer should be $14.40
The answer is 66%. You get the answer by multiplying 100 to 0.66.
You will find teh GCF of that this will give you 9(x3-3) now you can fator it teh factors of these can be (x2+1) and (x-3)
