1. If p(x) = 3x + 4x² - 5x +8, find p(-2).​
levacccp [35]

Step-by-step explanation:

\small{\underline{\tt{\red{Given}}}}

\rightarrow p(x) = -2

\small{\underline{\tt{\green{solution}}}}

\rightarrowp(x) = 3x +  {4x }^{2}  - 5x + 8

\rightarrowp( - 2) = 3( - 2) + 4( { - 2}^{2} ) - 5( - 2) + 8

\rightarrowp( - 2) =  - 6 + 16  + 10 + 8

\rightarrowp( - 2) = 10 + 18

\rightarrowp( - 2) =  28

\small\boxed{p(-2) = 28 }

Hope it helps

The length of one side of a square pond is 15 feet. The pond is surrounded by a 3 foot wide walkway. What is the total area of t
rewona [7]

Answer:

Area = 324 ft²

Step-by-step explanation:

Given

Length = 15ft

Walkway = 3ft

Required

Determine the area of the pond + the walkway

To calculate the required area, we need to get the total length of a side .

This is calculated by adding the length of a side of the pond and the side of the walkway

Total Length = Pond Length + Walkway

Total Length = 15ft + 3ft

Total Length = 18ft

Now, the required area can be calculated as thus:

Area = Total Length * Total Length

Area = 18ft * 18ft

Area = 324 ft²
