(а+1) (а+2)-(а+1)(а-2)-а-1

umka21 [38]

If you would like to calculate (a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1, you can do this using the following steps:

(a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1 = a^2 + 2 * a + 1 * a + 2 - (a^2 - 2 * a + 1 * a - 2) - a - 1 = a^2 + 3 * a + 2 - a^2 + 2 * a - 1 * a + 2 - a - 1 = 3 * a + 3

The correct result would be 3 * a + 3.

If you ran exactly one mile, how many feet did you run?

leonid [27]

You ran approximately 5278 feet. This question only involving converting units. 1 mile=1.609km=1609m. 1m=3.28 feet. So 1 mile=1609*3.28=5278 feet approximately.

Give the following equations determine if the lines are parallel perpendicular or neither

GaryK [48]

In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.

Let's start with the first equation.

$\frac{6x-5y}{2}=x+1$

Cross multiply both sides of the equation.

$6x-5y=2(x+1)$ $6x-5y=2x+2$

Subtract 6x on both sides of the equation.

$6x-5y-6x=2x+2-6x$ $-5y=-4x+2$

Divide both sides of the equation by -5.

$-\frac{5y}{-5}=\frac{-4x}{-5}+\frac{2}{-5}$ $y=\frac{4}{5}x-\frac{2}{5}$

Therefore, the slope of the first equation is 4/5.

Let's now simplify the second equation.

$-4y-x=4x+5$

Add x on both sides of the equation.

$-4y-x+x=4x+5+x$ $-4y=5x+5$

Divide both sides of the equation by -4.

$\frac{-4y}{-4}=\frac{5x}{-4}+\frac{5}{-4}$ $y=-\frac{5}{4}x-\frac{5}{4}$

Therefore, the slope of the second equation is -5/4.

Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.
