Answer:
x = 19
Step-by-step explanation:
The marked (consecutive interior) angles will be supplementary when the lines are parallel.
(3x +10)° +(5x +18)° = 180°
8x = 152 . . . . . . . . . . . . . . . divide by °, subtract 28
x = 19 . . . . . . . . . . . divide by 8
Answer:
U = x + 3 and V = 7
Step-by-step explanation:
Let U = x + 3 and V = 7, then:
=> (x + 3)^2 + 14(x + 3) + 49
= (x + 3)^2 + 2*7*(x + 3) + 7^2
= U^2 + 2UV + V^2
= (U + V)^2
(correct)
Let, the number = x
8x-10 ≥ 6x+14
Subtracting 6x form both sides,
2x-10 ≥ 14
Adding 10 to both sides,
2x ≥ 24
Dividing by 2,
x ≥ 12
