Answer:
x = 5
Step-by-step explanation:
The line segment divides the sides in proportion, that is
= ( cross- multiply )
10(2x - 3) = 14x ← distribute left side
20x - 30 = 14x ( subtract 14x from both sides )
6x - 30 = 0 ( add 30 to both sides )
6x = 30 ( divide both sides by 6 )
x > 48/5 the first one is false
x=47
-65
-80 - -15
Two minuses become plus
= -80+15
Subtract and keep the sign of the higher number
= -(80-15)
= -65
Total area = 12 + 18 = 30cm²
