Answer:
(3x+1)(5x-2)
Step-by-step explanation:
Given the expression
15x^2-6x+5x-2
Factorize;
3x(5x-2)+ 1(5x-2)
(3x+1)(5x-2)
Hence the factorized form is (3x+1)(5x-2)
Answer: 2(3x^2-5x-1) or 6x^2-10x-2
Step-by-step explanation: combine like terms, and then factor by grouping :)
Answer:
The volume is decreasing at a rate of 48 cubic meters per year.
Step-by-step explanation:
We are given the following information in the question:
A pyramid has height h and a square base with side x.
The height of the square pyramid remains constant.
The side of the base is decreasing by 0.004 meter/yr
We have to find the rate at which the volume is decreasing when the height is 120 meters and the width is 150 meters.
The volume is decreasing at a rate of 48 cubic meters per year.
