1) 2x + 9 = 2x -5
9 ≠ -5 ; No solution
2) 2x- 1 = x + 3
x = 4; One solution x = 4
3) x + 2 = x + 2
0 = 0; Identity (or all real numbers)
Geometry helps us in deciding what materials to use, what design to make and also plays a vital role in the construction process itself. Different houses and buildings are built in different geometric shapes to give a new look as well as to provide proper ventilation inside the house.
Hope that helped :)
Answer:

Step-by-step explanation:
Tan θ =
= 
So, Perpendicular = b, base = a
<em><u>Finding hypotenuse by Pythagorean Theorem:</u></em>

=> So, <u><em>hypotenuse = c</em></u>
Sin θ = 
Cos θ = 
So, <u><em>Now finding </em></u>
=>
÷ 
=>
÷ 
=> 
=> 
Answer:
40
Step-by-step explanation:
1/4 is one fourth of 1 cup then multiple that by 10. 4x10 =40
Vertex is

and minimum value of f(x) is 12
