x - y = 12 ⇒ 3x - 3y = 36
2x + 3y = 76 ⇒ 2x + 3y = 76
5x = 112
5 5
x = 22.4
x - y = 12
22.4 - y = 12
- 22.4 - 22.4
-y = -10.4
-1 -1
y = 10.4
(x, y) = (22.4, 10.4)
Answer:
= (xa+b)a-b .(xb+c)b-c. (xc+a)c-a
Or
= x(a+b)(a-b). x(b+c)(b-c) .x(c+a)(c-a)
Answer:
The answer is C) -2 and 6
Step-by-step explanation:
x+4 / -3x^2 + 12x + 36
= x + 4 / -3 ( x^2 - 4x - 12)
= x - 4 / -3(x - 6)(x + 2)
the excluded values make the denominator = 0
so the answer is -2and 6
Answer:
1728 inches
Explanation:
There are 3 feet in 1 yard and 12 inches in 1 foot, so we have:
48 yards * 3 = 144 feet
144 ft * 12 = 1728 inches
Emily bought 1728 inches.

An irrational number is a number that can't be written as a simple fraction while a rational number is a number that can be written as the ratio of two integers, that is, as a simple fraction. So in this case we have the number 2 which is ration, and we can multiply it by an irrational number 
such that the product is an irrational number. So any irrational number will meet our requirement because the product of any rational number and an irrational number will lead to an irrational number. For instance:
