the length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if it’s area is 114 sq
Novosadov [1.4K]

Answer:

w = 19

L = 6

Step-by-step explanation:

L = w - 13

a = lw

114 = w(w - 13)

114 = w² - 13w

w² - 13w - 114

(w - 9) (w + 6)

w ≠ -6 (a length cannot be negative)

w = 19

L = 19 - 13

L = 6

determine if the quadratic equation has 2 solutions, one, or 2 imaginary solutions by using the descriminant
Maurinko [17]

Hello from MrBillDoesMath!

Answer:

31a.  2 real roots

31b   2 complex roots

Discussion:

31a.

2x^2 + 3x - 6 = 0

Using standard quadratic notation, the above equation has a  = 2, b = 3 and c = -6. The discriminant is given by b^2 - 4ac, which is

3^2 - 4*2*(-6) = 9 + 48 = 57 > 0, so the quadratic has 2 real roots


31b.

The equation is equivalent to  16x^2 + 10x  +3 = 0. Its discriminant is

10^2 - 4 * (16) * (3) = 100 - 192 = -92 so this equation has two complex roots



Regards,  

MrB
