The equation that would represent the new area N of the floor of the cage would be
N=w2+4w which would be a
Answer:
D
Step-by-step explanation:
Lateral SA = area of the 4 triangles
Formula to be used :-
Area (triangle) = 1/2bh
=> 4 x 1/2 x 9 x 12
=> 108 x 2
=> 216 cm²
Total SA = LSA + area of the square
Formula to be used :-
Area (square) = side length x side length
=> 216 + 9 x 9
=> 216 + 81
=> 297 cm²
<u>The correct option is (D).</u>
Answer:
The value of the expression at w=3 is;

Explanation:
Given the expression;

Then when w=3, the value of the expression is;

The value is gotten by replacing/substituting w with 3 in the expression;
Therefore, the value of the expression at w=3 is;
