Answer:
x = ±
Step-by-step explanation:
Given
5 - 2x² = - 15 ( subtract 5 from both sides )
- 2x² = - 20 ( divide both sides by - 2 )
x² = 10 ( take the square root of both sides )
x = ±
Use the table to find the slope. -2 2 1/2 -1/2

Total weight of the steel gate = 150 kg
Solution:
Length = 12 m
Breadth = 5 m
Using Pythagoras theorem,
Diagonal =
Diagonal = 13 m
Total length of the gate = 5 + 5 + 12 + 12 + 13 + 13
Total length of the gate = 60 m
Weight of the steel per meter = 2.5 kg
Weight of the steel for 60 m = 60 × 2.5
= 150 kg
Total weight of the steel gate = 150 kg
Subtracting from both sides gives us the false statement
so this equation can never be true and thus has no solutions.
