1/x+5
Step-by-step explanation:
1. Rewrite 3x as a difference
x-2/x^2 + 5x-2 - 10
2. Factor out x from the equation, then factor out -2.
x-2/ x+(x+5) - 2(x+5)
3. Factor out x+5 from the expression
x-2/ (x+5)(x-2)
4. Reduce the fraction with x-2
x-2 / (x+5) x-2
1/x+5

Step-by-step explanation:
80t+500=30t+700
-30t -30t
50t+500=700
-500 -500
50t=200
/50 /50
T=4
A=80(4)+500=820
B=30(4)+700=820
Answer:
18cm
Step-by-step explanation:

DE = 6 × 3 = 18 cm
or
DC/CB = x/AB
7.5/2.5 = x/6
3=x/6
x=6×3=18 cm
