Answer:
1. a. 3xy²(7x²y³ + 5x - 4y)
2. a. (3x + 2)(5x + y)
3. d. (2a + b)(5x - 4)
Step-by-step explanation:
For #1, your answer was missing an exponent, which I boldfaced. Every term has a <em>y</em><em>²</em><em> </em>in common. Then, in numbers 2 and 3, just factor each group one at a time.
Ex: [10ax + 5bx] - [8ay - 4by]
Answer:
u take the 3.0 and then x it by 3 that should be the answer
Step-by-step explanation:
As given;
2.52x10^7 people are living in <span>4.05x10^5 km^2 area. then for 1km^2, the number of people can be calculated as:
people in 1km^2 = (2.52x10^7) / (</span><span>4.05x10^5)
=0.62x10^2
or
=6.2x10^1</span>
