Simplify (-2)(-3)^2 -2(2 - 5)

Answers

Answer 1

Answer: When solving this problem, PEMDAS is a key component. What is PEMDAS?
PEMDAS stands for the following:
P- Parentheses
E- Exponents
M-Multiplication
D- Division
A-Addition
S-Subtraction
This is also known as order of operations. Following this order, we can easily simplify the problem.

P-Parentheses
(-2)(-3)^2-2(2-5)
Our parentheses is (2-5). We can simply this to -3. Our problem now is
(-2)(-3)^2-2(-3)

E-Exponents
We have one set of exponents in this. It is -3^2. This simplifies to 9. Our problem now is
(-2)(9)-2(-3)

M- Multiplication
We can simply to.
-18+6

These simplifies into
-12

Answer 2

Answer:

Final answer:

To simplify the expression (-2)(-3)^2 - 2(2 - 5), you perform the calculations step by step. The final result is -12.

Explanation:

To simplify the expression (-2)(-3)^2 - 2(2 - 5), we perform the calculations step by step:

First, we calculate (-3)^2, which is equal to 9.
Next, we substitute the values in the expression: (-2)(9) - 2(2 - 5).
Then, we simplify the expression inside the parentheses: (-2)(9) - 2(-3).
Multiplying -2 by 9 gives us -18, and multiplying 2 by -3 gives us -6.
Finally, we subtract -6 from -18 to get the final result, which is -12.

Therefore, the simplified expression is -12.

A vegetable garden and a surrounding path are shaped like a square that together are 11 feet wide. The path is 2 feet wide. Fins the total area of the veget garden and path.

Answers

The area of a square is found by S^2 where S is the length of a side.

The garden and path are 11 feet wide, so the total area for both is 11^2 = 121 square feet.

The length of a side of just the garden would be 11 - 4 ( 2 feet of path on both sides) = 7 feet

The area of the garden would be 7^2 = 49 square feet.

the area of the path would be the total area minus the area of the garden: 121-49 = 72 square feet.
