A=WL
P=2(L+W)
A=(x)(14-x)
W=x
L=14-x
P=2((14-x)+x)
P=2(14-x+x)
P=2(14+0)
P=2(14)
P=28
perimiter=24 units
Answer:
y = 3/4x +4
Step-by-step explanation:
From point A to point B, you show a rise of 3 units and a run of 4 units. (The rise is the difference in height of the first two squares; the run is the side length of the first square.) The ratio rise/run = 3/4 is the slope of the line you want.
The upper-left corner of the first square is the y-intercept of the line (4). So, in slope-intercept form, the equation of the dotted line is ...
y = mx + b . . . . . m = slope; b = y-intercept
y = 3/4x + 4
Step-by-step explanation:
the answer is in the above image
Since they each paid the same amount, we can figure out that 9*4=36 dollars is the price of the gift. Next, since there was a 10% discount (or 0.1 by moving the decimal 2 spots to the left), we can say that the original gift price is x and
x-0.1*x=0.9*x due to that we subtract the 10% discount (and it's 10% of the original price). In addition, the sisters paid 0.9*x, which is 36. Dividing both sides by 0.9, we get x=40
