Answer:
The sequence of amountof water is geometric(first term
20, commonratio
0.5) but the se-quence of antifreezeis not (a geometricsequence cannot havezero as its first termsince that would implythat all terms are zero).

Answer:
A':A = 1742:7
Step-by-step explanation:
Applying,
A' = L'W'............... Equation 1
Where A' = Area of the window, L' = Length of the window, W' = Width of the window.
From the question,
Given: L' = 312 ft, W' = 134 ft
A' = (312×134)
A' = 41808 ft²
Similarly,
A = LW.................. Equation 2
Where A = Area of the image of the window, L and W is thw length and width of the image of the window
Given: L = 12 ft, W = 14 ft
Therefore,
A = 12×14
A = 168 ft²
Therefore the ratio of A' to A = 41808:168 = 1742:7
A':A = 1742:7
Step-by-step explanation:
3(6+b)+2b+1
18+3b+2b+1
5b+19
Add 6.5 to both sides
D=-0.7
A
