Hi! There is a lot to answer but I will answer all the questions I can!

I hope this helps!

• When we multiply the variable, we add the exponents
• We multiply to get rid of the brackets
• Once the brackets have been removed, we factor to simplify

Example:

-10x(2x^2 - 4x)

-20x^3 + 40x^2

20x^2(-x + 20)

a) Area = Length * Height

= 4x(5x - 2) = 20x^2 - 8x

b) x = 7 cm

4(7)[5(7) - 2] = 28[35 - 2] = 924 cm squared

c)

i) 4x + 4x + (5x - 2) + (5x - 2)

= 8x + 10x - 4

= 18x - 4

ii) P = 2l + 2w

2(4x) + 2(5x - 2)

8x + 10x - 4

= 18x - 4

d) x = 2

18(2) - 4 = 32

= 32cm

World Problem #2

5x+3y-2 = 2x+4y-3-x+7y-4+s

Find s

s = 5x-x+3y-11y-2+7

s = 4x - 8y + 5

I really hope this helps!!!!

I have to go so I won't be able to answer the rest of the questions today!

I will come back and answer them tomorrow!!! Let me know if you need them ASAP, I could try to make some time.

y = mx + b

m = y2 - y1/x2 - x1

y2 = -4

y1 = 5

x2 = 0

x1 = -3

m = -4 - 5/0 - (-3)

m = -9/3 = -3

y = -3x + b

Substitute (0, -4) into the equation:

-4 = -3(0) + b

Solve for b:

b = -4

m + b = -3 + -4 = -7

The answer is -7

I hope this helps!

Thank you so much! I wanted to make sure because my teacher solved it another way which gives us another answer.

But thank you so much!

Thank you for helping me!! I really appreciate it!

:)

I did not know that! Thank you for letting me know!

Hi! That sounds like a great idea!

2sqrt(17)

I hope this helps!!

The answer is:

21

Each point connects 6 other points. But without overlapping the points, 21 points is the correct answer.

Draw a circle and try it out yourself!

I hope this helps!
