Eliminate parenthesis by using the distribution property
= 5x² -3x +3 - x² - 2x +1
Group similar terms
= (5-1)*x² + (-3 -2)*x + (3+1)
Then sum everything:
= 4x² -5x +4
I’m assuming you need to write an equation to display the relationship.
y=20x+50
The bear can walk at a rate of 2 mph, which means after 4 hours it could have traveled 8 miles. That is our radius. To calculate the area of a circle, remember the formula
A =

r^2
3.14 * 8^2 = A
3.14 * 64 = A
200.96 = A
An area of
200.96 square miles must be searched.
Answer:
<h2>
width = 3 feet</h2>
Step-by-step explanation:
Let h be the height of the door
and w be its width
The statement “The height of the door is I foot more than twice its width”
can be translated mathematically like this : h = 2w + 1
Let’s solve the equation for w:
h = 2w + 1
⇔ 2w = h - 1

now , if the door is 7 feet high then it’s width is equal to :

A and D I think or it may just be A
