I am assuming the expression is (2x-3)(x+5) or (2x-3)(x-5). I will teach you how to solve for both as I am not sure which one you are asking for. There are 4 steps to multiplying.
1) Multiply the x times the second x
2) Multiply x times the second number
3) Multiply the number by the second x
4) Multiply the number by the second number.
(2x*x)+(2x*5)+(-3*x)+(-3*5)=(2

)+(10x)+(-3x)+(-15)=2

+7x-15
(2x*x)+(2x*-5)+(-3*x)+(-3*-5)=(2

)+(-10x)+(-3x)+(15)=2

-13x+15
Your answer is 2

+7x-15 or 2

-13x+15. Does that answer your question?
I think the answer maybe 9t+5x
If you're comparing 1.435 * 10^(-3) mm to 1.435 * 10^3 mm, then the more reasonable measurement is 1.435 * 10^3 mm since,
1.435 * 10^3 mm = 1435 mm = 1.435 meters
1 meter is about 3.28 feet approximately
So 1.435 meters is slightly larger (about 4.708 feet) which is a fairly reasonable distance between the tracks on a railroad.
-------------------
Something like 1.435 * 10^(-3) mm is equal to 0.001435 mm, which is far less than 1 mm.
The lateral area of the prism equals to height * perimeter of the base. So the lateral area is 160 cm2. And the surface area of the prism equals to the area of the base*2+the lateral area= 202 cm2.
