Answer:
The solution for the given expression is 0 , 2
Step-by-step explanation:
Given expression as :
- x² + x = 0
or, - 2 x² + 4 x = 0
or, 2 x ( -x + 2 ) = 0
or, ( - x + 2 ) ( 2 x ) = 0
or, 2 x = 0
∴ x = 0
and ( - x + 2 ) = 0
Or, - x = - 2
∴ x = 2
Hence The solution for the given expression is 0 , 2 Answer
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same
This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6
