Answer:

- 8x + 8

Step-by-step explanation:

(x - 3)² - (x + 1)² ← expand factors using FOIL

= x² - 6x + 9 - (x² + 2x + 1) ← distribute parenthesis by - 1

= x² - 6x + 9 - x² - 2x - 1 ← collect like terms

= - 8x + 8

-4=x/20-5 Solve for x
garik1379 [7]

Answer:

x = 20

Step-by-step explanation:

I'm no mathematician but...

- 4 = x / 20 - 5

If you move the five to the other side using addition you get:

1 = x / 20

Then multiply 20 on both sides

20 = x

Tegan needs to make 68 more snow blocks to finish building an igloo.
Setler [38]

We are given:

The number of blocks Tegan still needs to make = m.

The number of blocks Tegan has completed = c.

Total number of more snow blocks need to make = 68 .

Total number of more snow blocks need to make = Total number of blocks -  The number of blocks Tegan has completed.

m = 68 - c.

Therefore, the equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks is

<h2>m = 68 - c.</h2>
