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
Sorry for bad drawing but I think that shows it
2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)
Answer:
I believe it is rational
Step-by-step explanation:
irrational is a number that continues and never has an end i believe.
P^2-8p+7p-56
First I foiled. This meaning that I multiplied the first numbers in each pair of parentheses, then I multiplied the outside numbers, then the inside numbers and finally the last numbers.
p^2-p-56
Second I combined like factors.
This should be your final answer, keep in mind that ^2 means squared.
p^2-p-56
