5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- x²+y²<span>=74
xy=35
2. Therefore, you have that (x-y)</span>² is:
=(x-y)²
=x²-2xy+y²
=(x²+y²)-2xy
3. When you substitute the values given in the problem, you obtain:
=74-2(35)
=74-70
=4
4. Therefore, as you can see, the correct answer is: 4

Answer:
(2x -3)(2x -1)
Step-by-step explanation:
We have filled in the X-diagram so the side values have a product equal to the top value, and a sum equal to the bottom values (the middle term).
We're not sure how you've been taught to split the leading coefficient to arrive at the factors shown on the right.
Standard form means write the normal way so the answer is 256,000
