Answer: 14x - 11

Step-by-step explanation:

Add  10x and 4x.

14x −15 + 4

Add −15 and 4.

14 x −11              

OR.

Apply the distributive property. 5 ( 2 x ) + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply  2  by  5 . 10 x + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply  5  by   − 3  . 10 x − 15 + 4 ( x + 1 )

Apply the distributive property. 10 x − 15 + 4 x + 4 ⋅ 1

Multiply  4  by  1 . 10 x − 15 + 4 x + 4

hoped this helped lmk if it did

Anyone, I need help... Just answer the 6 (c)....and also proper working.☺️

Answer:

(i) The area of the rabbit cage when the width is 5.2 m is 81.5 m²

(ii) The area of the rabbit cage if Wilson has 40 meters of wire mesh is 75 m²

Step-by-step explanation:

(i) The given relation of the area, A to the width P of the rabbit cage is A = 3·p²

The graph of the function between the values of 0 and 6 inclusive is found as follows;

A,              3·p²

0,               0

1,                1

2,               12

3,               27

4,               48

5,               75

6,               108

Please find attached the graph of A to 3·p²

From the graph, we have when the the width, p, of the rabbit cage = 5.2, the area, A ≈ 81.5 m²

The area of the rabbit cage when the width is 5.2 m = 81.5 m²

(ii) Also from the graph given that the total wire mess with Wilson = 40 meters, we have;

The formula for the perimeter of the cage = The formula for the perimeter of a rectangle = 2×length + 2×width

The formula for the perimeter of the cage = 2×3×p + 2× p = 8·p

Where the total length of the wire mesh available = 40 meters for the cage

The 40 meters of wire mesh will be used round the perimeter of the cage

∴ 40 m. = 8·p

p = 40/8 = 5 m.

At p = 5 m. the area is given as A = 75 m².

Therefore, the area of the rabbit cage if Wilson has 40 meters of wire mesh = 75 m².
