L=2w-3
65=w(2w-3)
65=2w²-3w
2w²-3w-65=0
2w²+10w
2w(w+5)
-13w-65
-13(w+5)
(2w-13)(w+5)
w=13/2
l=13-3
l=10
The width is 13/2 yd, and the length is 10 yd.
Answer:
4x4 - x3 + 7x2 + 13x - 10
Step-by-step explanation:
(((4•(x4))+7x2)+6x)-(x3-7x+10)
((22x4 + 7x2) + 6x) - (x3 - 7x + 10)
3.1 Find roots (zeroes) of : F(x) = 4x4-x3+7x2+13x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -10.
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,2 ,5 ,10
Final result :
4x4 - x3 + 7x2 + 13x - 10
hope this helps:)sorry if it doesnt
