Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2
Answer:
$11 approx
Step-by-step explanation:
Given data
Total cost of album= $11.65
Tax= 6%
Let the cost of the album without tax be x
x+ 6/100*x=11.65
x+0.06x=11.65
1.06x=11.65
x= 11.65/1.06
x=10.99
Hence the cost is $11 approx
Answer:
Using the Quadratic Formula
x=-b ± √b²-4ac/[2a]
x= -(-5) ± √5² - 4(1)(5)/(2)
x= 5 ± √25-20 /(2)
x= 5 ± √5 /(2)
x= 5 + √5/(2) and 5 - √5/(2)
