Answer:
13 cm wide; 15 cm long
Step-by-step explanation:
Let w represent the original width. Then the original length is (w+2) and the original area is w(w+2). After the decrease, the width is (w-1) and the length is (w+1). The decreased area is (w-1)(w+1). The difference between these areas is 27, so we have ...
w(w+2) -(w-1)(w+1) = 27
w^2 +2w -(w^2 -1) = 27
2w +1 = 27
w = (27-1)/2 = 13
The original piece of cardboard was 13 cm wide and 15 cm long.
Answer:
The units of measurement for the composite function c(w(h)) is canvases over weeks.
Step-by-step explanation:
Given :
The function c(t) approximates how many canvases she paints per hour.
The function w(h) represents how many hours per week Christina spends painting the canvases.
To Find: What are the units of measurement for the composite function c(w(h))?
Solution:
C(t)= canvases paints per hour
W(h)=hours per week
C(w(h)) =canvases paints per hour * hours per week
C(w(h)) =canvases per week
So, Option 3 is true
Hence , the units of measurement for the composite function c(w(h)) is canvases over weeks.
