Artist 52 [7]
The answer for the exercise shown above is the option  B, which is: x^{7} -4 x^{5} +2 x^{4} +4 x^{3}- 10
 
The explanation is shown below:
 To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is 7
 and the lowest degree is 0
(Because -10 x^{0} =-10(1)=-10. Therefore, you have that the correct option is the option B.

The height of a triangle is 7 cm longer than its base.
katrin [286]
A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B)  .5*height^2  -3.5*height = 60
B)  .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60
