Answer:
Part A: 5x² + 7x - 4
Part B: 5x³ - x² - 8x + 1
Part C: Yes.
Step-by-step explanation:
Part A: The length of two sides of a triangle are given by
Side 1: 3x² - 2x - 1
Side 2: 9x + 2x² - 3
Now, the total length of the two sides, 1 and 2, of the triangle will be
= (3x² - 2x - 1) + (9x + 2x² - 3)
= 5x² + 7x - 4 (Answer)
Part B: If the length of the third side is y and the perimeter of the triangle is (5x³ + 4x² - x - 3), then
y = (5x³ + 4x² - x - 3) - (5x² + 7x - 4) = 5x³ - x² - 8x + 1 (Answer)
Part C: The answers in the part A and part B are closed under addition and subtraction. (Answer)
= 34y = 1156
Divide both sides by 34
Y = 1156/34
Simplify 1156/34 to 34
Y = 34

Answer:1.--63 dollars
6 months-108
1 year=216
Step-by-step explanation:18 times 6 is 108 and 108 times 2 is 216
The smallest angle is opposite the smallest side. Therefore the smallest angle is <S
The largest angle is opposite the largest side. Therefore the largest angle is T.
The order that these should go is
S<R<T. That makes B the answer.
