Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
Answer:-80
Step-by-step explanation:f(x)=2*2+4*-10
Answer:
42/49 is the fraction
Step-by-step explanation:
you can't simplify so put the amount correct over the amount total.
Answer:
Step-by-step explanation:
<u>Multiply and simplify:</u>
- (x - 1)(x + 2)(x + 3) =
- (x² + 2x - x -2)(x + 3) =
- (x² + x - 2)(x + 3) =
- x³ + 3x² + x² + 3x - 2x - 6 =
- x³ + 4x² + x - 6
<u>From the final polynomial we can see that:</u>
- a = 1, b = 4, c = 1 and d = - 6
So all the coefficients are positive but the constant d is negative
Answer: 10 verticesTo make a full circle(360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines.Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9= 10
If the question saying literally 40 edges(not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41
