Answer:

Step-by-step explanation:
a trinomial that cannot be factored has no real roots.
here is one:

After graphing this trinomial has no intersections points with the x-axis wich means it has no roots
Answer:
there is no solution
Step-by-step explanation:
y + 7 = 3x
6x - 2y = 6 which can be simplied to be 3x - y = 6 (divide by 2)
let y = 3x - 7
substitute: 3x -(3x - 7) = 6
3x - 3x + 7 = 6
7 ≠ 6 therefore, no solution
Answer:
Step-by-step explanation:
You have to use the triangle inequality theorem:
12cm, 4cm, xcm
x > 4cm - 12cm
x > -8cm
x < 12cm - 4cm
x < 8cm
-8cm < x < 8cm
Answer:
42 square meters
Step-by-step explanation:
rectangle: 3 x 6= 18 square meters
square: 4 x 5= 20 square meters
triangle: 4 x 2 x 1/2= 4 square meters
18 + 20 + 4= 42 square meters
