Correct?! 4*2 + (10-12)

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
5 0

4 * 2 + (10 - 12)

Using PEMDAS, we solve inside the parentheses first.

10 - 12 = -2

If it was 12 - 10, the answer would be 2. But because 10 is on the left side, the answer is -2

Next, we have 4 * 2.

4 * 2 = 8

And finally, 8 + (-2) = 6.

Because we're adding a negative number, it subtracts from the positive number.

Use the GCF and the Distributive Property to express the sum as a product. 30 + 10
Inessa [10]

The expression that uses the GCF and the Distributive Property to express the sum as a product of the expression given as 30 + 10 is 10(3 + 1)

<h3>How to use the GCF and the Distributive Property to express the sum as a product?</h3>

The expression is given as:

30 + 10

Express the terms of the expression as the product of their GCF.

So, we have:

30 + 10 = 3 * 10 + 1 * 10

Factor out 10

30 + 10 = 10(3 + 1)

Hence, the expression that uses the GCF and the Distributive Property to express the sum as a product of the expression given as 30 + 10 is 10(3 + 1)

Find the 50th term for the sequence 31,24, 17
Nikitich [7]

9514 1404 393

Answer:

  -312

Step-by-step explanation:

The general term of an arithmetic sequence is ...

  an = a1 +d(n -1)

Here, you have first term a1 = 31, and common difference d = 24-31 = -7. So, the 50th term is ...

  a50 = 31 -7(50 -1) = 31 -7(49) = -312

The 50th term for the sequence is -312.
