Answer:
321/8 ft^2
Step-by-step explanation:
The whole area is 49/4 × 5 = 245/4 ft^2
The area of tiled floor is 13/2 × 13/4 = 169/8
245/4 - 169/8 we need to equalise the bottom of fraction to subtract so
2/2 × 245/4 = 490/8
490/8 - 169/8 = 321/8 ft^2
10 plus 5x = 50(x=8)
62 times 2x = 128(x=31)
Answer:
Step-by-step explanation:
(x - 3)/2 = -1
x - 3 = -2
x = 1
(y + 7)/2 = -1
y + 7 = -2
y = -9
(1, -9) the other endpoint
Answer:

We can factorise the numerator with the difference of squares formula:
-----------------------------

Now we can factorise the denominator:


Cancel out the common factor of (p-5):

The area of a square is calculated by squaring the length of the sides (multiplying by itself). Therefore, in order to find the length, you must find the square root of 225.
The square root of 225 is 15. Therefore, you length of each side is 15 feet.
p.s. I don't know how old you are, but I would recommend trying to memorise your square numbers up to

. I know I found that incredibly useful when it came to my exams last year (GCSEs)
