Factor out the GCF
15x^2+20x
15x^2/5x= 3x
20x/5x= 4
Final answer: 5x(3x+4)
Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.

Answer:
Equation: 48t + 265 = 553
t = 6
Step-by-step explanation:
48t + 265 = 553
48t = 228
t = 228/48
t = 6
5 can stay as is, but 5503 can be rounded to 5500 so 5500x5=27500
