Answer:
l = 6
+ 2a - 1
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
given A = 18
+ 6a² - 3a and w = 3a , then
3aw = 18 + 6a² - 3a ( divide each term by 3a )
w = 
+ 
- 
= 6 + 2a - 1
Answer:
y-y1=m(x-x1)
Step-by-step explanation:
It's best to memorize this formula, because you'll see this very often in Algebra I class. This is the point-slope form where m=slope.
The percent increase in area of the picture is 40.33%
Step-by-step explanation:
Original area of the rectangular picture that measures 6 in by 9 in will be
Area= L*W
Area= 6*9= 54 in²
Increasing the dimensions by 1+ 1/3 larger will be
6+1+1/3 = 22/3
9+1+1/3=31/3
New area= 22/3 * 31/3 =682/9 = 75.78 in²
Increase in area = 75.78 - 54 = 21.78
Percent increase in area= percent increase/original area *100
Percent increase in area= 21.78/54 *100 = 40.33%
