For this question it is the difference of two perfect squares. This means your final answer will be (2x - 5)(2x + 5). This answer is not listed so it would be none of the above.
After review, B technically works because it is the difference of two perfect squares. This allows you to take the square root of each term while ignoring the sign and then place that back in with the original sign.
Answer:
8 and 6
Step-by-step explanation:
If you use x for the first number, and y for the second, you get equations of 3x+5y=54 and x-2=y.
You can substitute the second equation into the first one to solve it. This gives 3x+5(x-2)=54.
The brackets can be expanded to 3x+5x-10=54. Collecting like terms makes it 8x-10=54.
Next, we add 10 to both sides. This gives 8x=64.
From there, we isolate the x by dividing both sides by 8, giving x=8.
To work out the second number, we can sub 8 for x in either equation (I'm using the second one as it's simpler).
This comes to y=8-2, therefore y=6.

Answer:
2d or 2 dimensional is the answer i think
Step-by-step explanation:
since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together
0.45×300= 135 2,335 - 135=2,200 2,200÷55= 40
⬆ ⬆ ⬆
This is how This is how much This is how many
much they paid was left in the days they paid for food
for the miles reimbursement and lodging
traveled
Part A: X= (2,335- ( 0.45 ×300) ) ÷55
Part B: I dont know how to do algebraic property of equality.
Part C: They spent 40 days or 1 month , one week and 3 days
Answer:
Step-by-step explanation:
8x = 8 * x
8 = 8 * 1
Greatest common factor = 8
8x + 8 = 8(x+ 1)
