Answer: d = 4t - 10
====================================================
Each side of the square picture frame is t centimeters long. The perimeter is t+t+t+t = 4*t centimeters long, which is just the entire distance around the frame. If we had the perfect amount of ribbon, then d = 4*t would be the end of the problem; however, we're 10 cm too short meaning that d is too small and it's actually d = 4*t - 10
For example, let's say that t = 12 meaning that the perimeter is 4*t = 4*12 = 48 cm. This would mean we have d = 4*t-10 = 4*12-10 = 48-10 = 38 cm of ribbon, and we're 10 cm too short (comparing 38 to 48).
note: d = 4t - 10 can be written as d = 4*t - 10
Answer:
f(-5)= 90, g(7)= -3x+4
Step-by-step explanation:
First Solve f(x)
f(x)= 3×^2-3x
Plug in -5 to the x
3(5)^2-3(-5)
f(x)= 90
Then Solve g(x)
g(x)=-3x+4
Plug in the 7 in the x
g(x)=-3x+4
g(x)=17
