It looks like you have to find N and then multiply each angle measure given to finds the correct angle measures. Remember, if you add up all of the interior angles in a triangle, it adds up to 180 degrees. So 3.2n + 6.4n + 2.4n = 180 degrees. You must solve for N. Combine all of them. The sum is 12n = 180 degrees. I'll let you solve for N. When you do, multiply each number in the triangle by N to find each angle measure. The formulas above are for the area of different geometric shapes, but won't help with this question.
Answer:
7y^2 +8xy -3
Step-by-step explanation:
Distribute the minus sign and combine like terms.
= 7y^2 +6xy +2xy -3
= 7y^2 +8xy -3
4/3? I am not sure though idk sorry for not being much help i am not great at math.
Answer:
Division
A polynomial divided by a polynomial is not necessary another polynomial. Therefore it is not closed
