Answer:

\frac{-\sqrt{65} - 3 }{4}, \frac{\sqrt{65} + 3}{4}

Step-by-step explanation:

Since we cannot factor the expression, we must use quadratic formula: x = \frac{-b +/-\sqrt{b^2 - 4ac} }{2a}

Plug in <em>a</em> for 2, <em>b</em> for 3, and <em>c</em> for -7 and you should find your roots.

The area of a rectangle is 44m2 , and the length of the rectangle is 3m
Grace [21]

Answer:

width=11/2

length=8

Step-by-step explanation:

44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>

44=2w^2 - 3w  <em>distribute</em>

2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>

(w+4)(2w-11) <em>factor</em>

width=11/2

(11/2 x 2) - 3

length = 8
