Answer:
0.2143 is the percentage
Step-by-step explanation:
Area of the rectangle = x^2 + 8x + 15 square units
Explanation:
Length = x + 5
Breadth = x + 3
Area = l x b = (x + 5)(x + 3) = x(x + 3) + 5(x + 3) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15 square units
Okay, to find that out, ignore the 3 in the 3 1/4 for now. So 1/4 right? Is 25% right? Out of four, 4/4 is? One. So bring back the three, do 3*4=12, so it equals: 13$ . not a good job right?
138 is divisible by 3 because if you add each integer: 1 + 3 + 8, you get 12. If 12 number is divisible by 3, than the whole number is. Since it is, 138 is divisible by 3.
For every one mile (across) the line will go up 60. This line (from (0,0) ) is therefore y = 60x
