Answer:

3. x + 18.

4. 8n + 16

Step-by-step explanation:

3. We have to calculate the area of wood present in the frame whose dimensions are given with the question.

Requires area = {(x + 3) × 1} + [(4 - 1) × {(x + 3) - (x - 2)}] = x + 3 + 3 × 5 = x + 18. (Answer)

4. The sum of four consecutive odd numbers where 2n + 1 is the smallest odd number will be

= (2n + 1) + (2n + 3) + (2n + 5) + (2n + 7)

= 8n + 16 (Answer)

Answer:

y=2.5x-3

Step-by-step explanation:

first, we find the y-intercept, which is the number with a zero in the x

That would be -3

next, we find the slope

to do this, we have to take two numbers on the y side next to each other and subtract.

For this example we will use 7 and 2

7-2=5

And just to be positive, we will also do 12 and 7

12-7=5

Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2

Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.

Now we have 5/1 or just 5

Finally, to put that into the right format, we do y=5x-3

You're Welcome

Good Luck
