Step-by-step explanation:
Our polynomial is x²+30x +c with a missing value c
c should make this polynomial expression a perfect square
- Write the expression with a decreasing order of degrees
x²+ 30x+c
- write the terms as factors
x² + 2*15*x +c
- notice that the in the middle we have 2*15*x so our third term will be 15²
x²+2*15*x+15² ⇒ c = 15²=225
- arrange your perfect square
(x+15)²
Answer
(13+4) + (4.63+7.4)
Step-by-step explanation:
Use the commutative property to put the decimals together. Use the associative property to group the decimals and numbers together as shown in the answer.

Answer:
C. since 8, 15, 17 are pythagorean triples
Well, it would basically go from y to -y and x to -x
180, means if it was 10 to left and 3 down, it is now 10 to right and 3 up
(10,-3) to (-10,3)
