how do you use absolute value to find the distance between two points that have the same X-coordinates but different Y-coordinat

sdas [7]

So since x coordinates are same, we just have a horizontal distance to find (no fancy slanted lines)

so what you do is
|y1-y2|=distance

What is the solution to −1/4(d+1)<2

kogti [31]

Answer:

$d > -9$

Step-by-step explanation:

$-\dfrac{1}{4}(d + 1) < 2$

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

$-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)$

$d + 1 > -8$

Subtract 1 from both sides.

$d + 1 - 1 > -8 - 1$

$d > -9$

The length of a rectangular park is four timesfour times its width. The park is surrounded by a 33-foot-wide path. Let x denote

tiny-mole [99]

Answer:

A(x) = 4x^2 + 330x + 4356

Step-by-step explanation:

width of park: x

length of park: 4x

width + path width = x + 66

length + path width = 4x + 66

area = (x + 66)(4x + 66)

area = 4x^2 + 66x + 264x + 4356

area = 4x^2 + 330x + 4356

A(x) = 4x^2 + 330x + 4356
