Answer:
15
Step-by-step explanation:
Because this figure is a parallelogram, the diagonals bisect each other. This means that the diagonals cut each other perfectly in half, meaning that x and 15 have the same value. Hope this helps!
Answer:
The correct option is option A
A. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix
Step-by-step explanation:
The matrix in echelon form is not in a unique form, as such row reduction can yield an infinite amount of answers. However a row reduced echelon form is unique and will give the same answer in every order that the row operation is performed
The statement is false. Each matrix has only one unique row echelon form, therefore, the correct option is option A.
Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)
They sell 3 different flavors of ice cream and 22 toppings.
To find the number of choices, multiply the number of flavors and number of toppings.
3 flavors x 22 toppings = 66 different choices.
The correct answer would be D. 66
