1. A rectangle has an area given by A=x^2+5x+6. Find expressions for the possible lengths and width of the rectangle.
Veronika [31]
1.  x^2+5x+6 = (x+3)(x+2), which implies that the sides could be x+3 and x+2.  (There are theoretically an infinite number of side-lengths, though--in general, for any polynomial or reciprocal of a polynomial P(x), \frac{x+3}{P(x)} and P(x)(x+2) is valid.  However, the set provided makes the most sense.)

2.  Profit is the difference between cost and revenue.  For revenue, 0.0000x^2 = 0, so revenue equals 40x, so profit equals 26x-120,000.

1. What is the measure of each interior angle of a regular hexagon?
Volgvan

1. The formula is 180(n-2)/n, where n=sides. so hexagon has 6 sides, so it would be 180(6-2)/6=180(4)/6=720°/6=60° per side.

2. The sum of measures of ANY polygon is ALWAYS 360°

3.  Notice that there are 6 sides. This means the total interior angles are 720°. x=127°

4. now, it's talking about a SINGLE exterior angle. So the interior angle is always 360/n, where n=5 here, so 360=5=72°

Use inverse operations to love each equation--
Dominik [7]

a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81

b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
