Equivalent expressions are expressions that work the same even though they look different.
Examples of two equivalent expressions are:
-4(x + 2) and 4x + 8
-2y+5y−5+8 and 7y+3
These are equivalent expressions as they have the same value.
hope this helps,have a great day!!

Step-by-step explanation:
<u>Given:</u>
- Lemons - l and apples - a
- a = 35¢, l = 15¢
- Number of apples and lemons = 17
- Cost of lemons and apples = $3.95 = 395¢
<u>System as per question:</u>
- a + l = 17
- 35a + 15l = 395
Or
- a + l = 17
- 0.35a + 0.15l = 3.95
The surface area of the pyramid will be given as follows:
Area of triangles:
A=1/2×base×height
A=1/2×12×18
A=108 m²
Area of 6 triangles is given by:
A=108×6=648 m²
Area of the hexagon:
A=6×1/2×12×6√3
A=374.123m²
Total surface area:
SA=648+374.123
SA=1022.123 m²~1022 m²
Answer: C] 1022 m²
