Answer: 81

To get this answer, you do two things
1) Take half of the x coefficient 18 to get 9
2) Square the result from the previous step to get 9^2 = 9*9 = 81

This value is added on to get x^2+18x+81 which factors to (x+9)^2 confirming we have a perfect square trinomial

Hey there!

First solving the equation 2^3 . . .

To solve 2^3, multiply the number 2 three times:

2 x 2 x 2 = 8

To find area, multiply the two sides . . .

(Since a square has all sides the same length, multiply 8 x 8)

8 x 8 = 64 <-------

The area of the shape is 64 inches.

Hope this helps you.
Have a great day!

Delvig [45]

Step-by-step explanation:

How to find the sides of a right triangle

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

A police car accelerates quickly to 60 meters per second in order to pursue a minivan that is recklessly speeding along the high
o-na [289]
1. You have that:
 -The <span>police car accelerates 60 meters per second.
 - The minivan has a speed of 45 meters per second and is 600 meters ahead of the police car at the beginning of the chase.
 2. Therefore, you have:
 V1xt=V2xt-600
 V1 is the speed of the minivan and V2 is the speed of the police car
 3. The time is:
 t=-600/V1-V2
 t=-600/(45-60)
 t=40 seconds</span>
