For this case we have that by power properties it is fulfilled:
Now, we can rewrite the expression as:
We also have by definition of properties of powers that:
So:
Answer:
Option D
Answer: 54.16% of pizza is left.
Step-by-step explanation:
Since we have given that
Part of pizza ate by Mario =
Part of pizza ate by his pet =
So, total part ate by them is given by
Part of pizza left is given by
Percentage of pizza left is given by
Hence, 54.16% of pizza is left.
Simplify
3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)
Simplify brackets
3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2
Collect like terms
(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)
Simplify
4 - 2n^2 - 3n^3
Answer:
-3n^3 - 2n^2 + 4.
Step-by-step explanation:
(3-7n^2+3n^3)-(6n^3-1-5n^2)
First distribute the negative over the second parentheses:
= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2
Now simplify like terms:
= -3n^3 - 2n^2 + 4 (answer).
Answer:
w = 21
x = 13
y = -11
z = -16
Step-by-step explanation:
Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...
Thus, w = 17 - (-4) = 17 + 4 = 21
x = 12 - (-1) = 12 + 1 = 13
y = -3 -8 = -11
z = -2 -14 = -16
These are the values of w, x, y and z , respectively.
