Answer:
96 sq. m
Step-by-step explanation:
If the width is x, the length is x + 4 and since perimeter = 2 * (length + width), we can write:
40 = 2(x + x + 4)
40 = 2(2x + 4)
20 = 2x + 4
16 = 2x
x = 8 so x + 4 = 12, therefore the area is 8 * 12 = 96 square meters.
slope intercept form: y=mx+b
y=2x-3
slope is also m
b is the y-intercept
answer:
slope is 2
y-intercept is -3
point-slope equation - y+3= -3/5( x+5)
slope-intercept form- y= -3/5x +b
Answer: width = 42, length = 74
Step-by-step explanation: 42 + 32 = 74
42 + 42 + 74 + 74 = 232
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
