Solve for x: 2x^2+4x-16+=0

ella [17]

$2x^2+4x-16=0|:2\\
x^2+2x-8=0\\
\Delta=36\Rightarrow\sqrt{\Delta}=6\\
x_1=\frac{-b+\sqrt{\Delta}}{2a}\ \vee\ x_=\frac{-b-\sqrt{\Delta}}{2a}\\
x_1=2\ \vee\ x_2=-4$

The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x2 + 5x

nikdorinn [45]

Answer:

width: 15 inches; length: 20 inches

Step-by-step explanation:

The equation tells you the product of width (x) and length (x+5) is 300, so you're looking for factors of 300 that differ by 5.

300 = 1·300 = 2·150 = 3·100 = 4·75 = 5·60 = 6·50 = 10·30 = 12·25 = 15·20

The factors in the last pair on this list differ by 5, so we have ...

width = 15 inches
length = 20 inches
