The expression for (t) \Join (t+2) - (t+1) \Join (t+1) is ( t^{2} + t - 2 ) ( t^{2} + t - 6 ).

The given operation is \Join such that x Join y = (x+2)(y-3).

We are to apply the \Join operation in the given expression.

t \join (t+2) - (t+1) \Join (t+1) and find its final expression.

Using this operation: x Join y = (x+2)(y-3).

Let's find,

t \join (t+2)

Here,

x = t and y = t + 2

= ( t+2 ) ( t+2 - 3 )

= ( t + 2 ) ( t - 1 )


(t+1) \Join (t+1)

Here,

x = t + 1 and y = t + 1

= ( t + 1 + 2 ) ( t + 1 - 3 )

= ( t + 3 ) ( t - 2 )

t \join (t+2) - (t+1) \Join (t+1)

= ( t + 2 ) ( t - 1 ) - ( t + 3 ) ( t - 2 )

= ( t^{2} - t + 2t - 2 ) ( t^{2} - 2t + 3t - 6 )

= ( t^{2} + t - 2 ) ( t^{2} + t - 6 )

Thus the expression for (t) \Join (t+2) - (t+1) \Join (t+1) is:

( t^{2} + t - 2 ) ( t^{2} + t - 6 )

Mr. Suárez wants to paint his storage shed. He needs to calculate the lateral surface area of the shed so that he will know how
WINSTONCH [101]

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The picture is the complete question.

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²
