62 cm. plug in 4 for x. 2(5(4)-2))+2(3(4)+1))= 2(18)+2(13)= 36+26=62. Hope this helps!
It's not clear what polynomial you posted, but let's say you had the polynomial
5x^3+7x^2-9x+10
This is a cubic polynomial as the largest exponent is 3. The degree is also 3. The degree of the polynomial is equal to the largest exponent.
The equation is -2x-4. u can use y2-y1/x2-x1.
