Answer:
1/4w -1
Step-by-step explanation:
(1/2w +3) -(1/4w +4) = w(1/2 -1/4) +(3 -4)
= 1/4w -1

The distributive property applies. It is useful for distributing the minus sign and for collecting terms.
−1 1/5+(−3/5)
Convert -1 1/5 into improper fraction
-6/5+(-3/5)
Add -3/5 to -6/5. This would be the same as subtracting 3/5 from -6/5
<span>Final Answer: -9/5 or -1 4/5</span>
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !
