<u>Let's solve this problem step-by-step</u>:
- <em>x: it is the delta in the equation given in your picture</em>
<em />
<u>We know (7*10) - (7*x) is equivalent to the 7*(10-x)</u>
⇒ based on the Distributive Properties
<em />
<em> </em><u>So:</u>
<em> </em>
<u>Thus delta (the little triangle in this problem) in this case is 1</u>
<u></u>
<u>Answer: 1</u>
<u></u>
Hope that helps!

Answer:
The second one
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
Perimeter = 2L + 2W
Perimeter: 2W + 100 + 100
Perimeter: 2W + 200
Answer:The graph of F is shifted 3 to the left and 1 up
Step-by-step explanation:
On the x axis, negative is left, positive is right. On the y axis, negative goes down, positive goes up. X is negative, it goes to the left, and y is positive, it moves up. Hope this helps and good luck!
Answer:
The length of this rectangle is 8m.
Step-by-step explanation:
The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So
The problem also states that the perimeter is 22 meters. So:
.
Also, it states that I is the length and it is 2 meters more then twice it’s width. So
What’s its length?
The width is 3m. The length is in function of the width, so:
The length of this rectangle is 8m.
