1.) To simplify the expression (-1)(4 - c) using the distributive property, you need to multiply -1 by each term inside the parentheses.
(-1)(4 - c) = -1 * 4 + (-1) * (-c)
= -4 + c
Therefore, the simplified expression is: 4 - c, which is option A.
2.) Using the distributive property to simplify the expression 4(2x - 4):
4(2x - 4) = 4 * 2x + 4 * (-4)
= 8x - 16
So, the simplified expression is: 8x - 16, which is option C.
3.) Applying the distributive property to simplify (10 + 4y) 1/2:
(10 + 4y) 1/2 = (10 * 1/2) + (4y * 1/2)
= 5 + 2y
Hence, the simplified expression is: 5 + 2y, which is option A.
4.) To determine the subsets of real numbers to which -22 belongs:
A. Whole numbers: Whole numbers include all positive integers, zero, and their negatives. Since -22 is an integer, it is a whole number.
C. Integers: Integers include positive and negative whole numbers. As mentioned, -22 is an integer.
Therefore, the answer is A and C.
5.) An algebraic expression for the word phrase "6 times the difference of b and p" is given by:
6(b - p)
Hence, the algebraic expression is 6(b - p), which is option B.
6.) Simplifying the expression (5(14 - 2)^2) / 2:
First, evaluate the part inside the parentheses: (14 - 2) = 12
Then, square the result: 12^2 = 144
Substitute this value back into the expression: 5(144) / 2
Finally, divide: 720 / 2 = 360
Therefore, the simplified form of the expression is 360, which is option D.
7.) Evaluating u + xy when u = 18, x = 10, and y = 8:
u + xy = 18 + 10 * 8
= 18 + 80
= 98
So, the result is 98, which is option C.
8.) Given the area of a square field as 479 ft^2, to find the approximate length of a side:
Since the area of a square is equal to the length of one side squared, we can take the square root of the area to get the approximate length of a side.
Taking the square root of 479, we get approximately 21.886.
Rounding this to the nearest foot, the approximate length of a side is 22 ft.
9.) Simplifying the expression (7 + 5) + 4 x 13 - 2:
First, perform the multiplication: 4 x 13 = 52
Then, simplify the addition and subtraction: (7 + 5) + 52 - 2 = 12 + 52 - 2 = 62
So, the final result is 62.
