Hello,
<span>SA = s^2 + 2 × s × l
Base = 4
SA= 4^2 + 2 x 4 x l
SA= 16 + 2 x 4 x l
SA= 16 + 8 x l
Simplified, the surface area of a square pyramid with a base of 4 and an </span>unknown length/height (l) is SA= 16 + 8 x l.

The total amount Aisha would pay to paint her room is $54.
<h3>What is the cost of painting the rooms?</h3>
The first step is to determine the area of the walls. The walls have the shape of a rectangle. Thus, the formula for the area of a rectangle would be used to determine the area of the wall.
Area of the three walls without a door : 3 x (length x width)
3 x (2.4 x 5.2) = 37.44 m²
Area of the fourth wall with a door : area of the wall - area of the door
(2.4 x 5.2) - (2 x 0.8) = 10.88m²
Total area of the walls : area of the three walls + area of the wall with the door
10.88m² + 37.44 m² = 48.32 m²
The next step is to determine the number of tins that would be needed:
48.32 /12 = 4.03
5 tins would needed
Cost of the 5 tins: (4 x 12) + (0.5 x 12) = $54

No
There are an infinite number of possibilities.
White . . . any even number greater than 8 .
Blue . . . . (1.5) x (the number of white ones).
The smallest possible contents of the bag:
White . . . 10
Blue . . . . 15
Total . . . . 25 .
C. 3x-2 1. you split the second terms into two terrms.
2. factor out common terms in the first two terms, then in the last two terms
3. factor out the common term 3x-2
cancel out x-5
and your left with 3x-2
