Which options could be the next step in simplifying this expression?

1 answer:

7 0

<span>In adding, subtracting, multiplying and dividing numbers, always remember this rule: PMDAS (or parenthesis, multiply, divide, add, subtract). The P in PMDAS must come first. We must use an order of operations. In the problem given, (18 + 23) + 7, they must be added. However you have a parenthesis that has the numbers 18 and 23. You will add 18 and 23 first and then you will get 41. And so the answer is 41 + 7, letter B. </span>

Answer:

809, 708, 607, 506, 405, 304, 203, 102, 1, -100

Step-by-step explanation:

809, 708, 607, _____, _______

First term = 809

Second term = 708

Third term = 607

Difference between first term and second term = 809 - 708

= 101

Difference between second term and third term = 708 - 607

= 101

Therefore, the common difference is 101

Fourth term = 607 - 101

= 506

Fifth term = 506 - 101

= 405

Sixth term = 405 - 101

= 304

Seventh term = 304 - 101

= 203

Eighth term = 203 - 101

= 102

Ninth term = 102 - 101

= 1

Tenth term = 1 - 101

= - 100

809, 708, 607, 506, 405, 304, 203, 102, 1, -100

A square piece of cheese covers 8 square inches of a plate. What is the approximate length of one side of the cheese? Approximat

Maksim231197 [3]

The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
