#1 is asking you to draw the shapes listed in the categories.

So, all the yellow shapes go in the yellow box, and all the red shapes go in the red box.

Yellow shapes: Yellow square, yellow square

Red shapes: Red square, red triangle, red triangle

#2 is asking for a few things.

First, you find the group of shapes from #1 that has 3 shapes, and circle the correct one.

The red box has three shapes in it, so the correct group is red.

So, you have to circle the small box that says "red."

Then, you have to write the number 3 in the empty line.

3n+8=23 answer and the work to show the answer please

Answers

Answer: n = 5

Step-by-step explanation: To solve for n, we must first isolate the term containing n which in this problem is 3n.

Since 8 is being added to 3n, we subtract 8 from both sides of the equation to isolate the 3n. On the left, the +8 and -8 cancel out and on the right 23 - 8 is 15.

So we have 3n = 15.

Now we can finish things off by just dividing both sides of the equation by 3. On the left the 3's cancel and on the right 15 divided by 3 is 5 so n = 5 and you can check your answer by plugging 5 back in for n in the original equation which is shown below in bold.

3(5) + 8 = 23 or 15 + 8 = 23.

Answer:

n = 5

Step-by-step explanation:

3n + 8 = 23

- 8 - 8 Subtract 8 from both sides

3n = 15

n = 5 Divide both sides by 3
