Answer:
1.x^2
2.x+8
3.x
4. 8x
Step-by-step explanation:
Length of old is x inches.
Because it is square we have that area of the old canvas :
When we read : width of new is increased by 8 so : x+8
Length is x.
The difference of areas:
Old canvas : A1=
New canvas :
Now we can find A2-A1:
Answer:
1. c
2. b
3. a
4. d
5. e

simplify -7 - 35 to -42
divide both sides by -4
two negatives make a positive
simplify 42/4 to 21/2
Answer: x = 21/2.
