B is a times b
C is also a times b
sorry im stuck on the rest
Answer: y
=
−
2
x
+
1
This is because slope intercept from is "Y= mx+b" :)

- How do you simplify this?
- x²y+xy² / y²+2/5 × xy


Factor the expressions that are not already factored.

<u>How </u><u>to</u><u> factorise</u><u> </u><u>:</u><u>-</u>
<u>NUMERATOR</u> 

Factor out xy.

<u>DENOMINATOR</u> 

Factor out 1/5.

_____
Continuing...

Cancel out y in both the numerator and denominator.

Expand the expression.

This can further simplified to as 

2x+x-7+3x-20=87cm
6x-27=87
6x=114
x=19
Therefore the sides are:12cm, 38cm, and 37cm
