Answer:
12x^4-35x^3+45x^2-13x-15
Step-by-step explanation:
some issues with the signa
Answer:
Neither
Step-by-step explanation:
5 x -10 = -50
4 x 9 = 36
-50 + 36 = -14 and therefore can not be orthogonal
sqrt(25+16)=sqrt(41)
sqrt(100+81)=sqrt(181)
sqrt(41) x sqrt(181) is not equal to -14 so therefore it is not parallel
So the answer is then neither
-4.5 or -4.3 i’m not really sure i’m just estimating
Answer is D because C^2 ×D^2 the * mean ×
