See the attached picture:
I believe the shorter sides are 5 feet and the longer ones are 10. This is because when you add up the two shorter sides as 10, and the other two as 20, then add them up to 30. That's the perimeter. For the area, you would do 10•5 to get 50 for the area
Answer:
40cm
Step-by-step explanation:
A=s*s
A=10*10
A=100 cm^2
P=4*s
P=4*10
P=40 cm
"s" represents side
Part A.
y=4x+3
Part B.
11=4x+3
8=4x
2=x
2 dollars
Part C.
4(3)+4(2)=12+8=20
It would be enough if there is no sales tax.
Hope this helps!
Your fortune is "Only one fortune a day!"
Using the slip and slide method:
2x^2+5x-12
x^2+5x-24
(x+8)(x-3)
(x+8/2)(x-3/2)
(x+4)(2x-3)
Final answer: (2x-3)(x+4)
