For this specific equation we have to use something called factor by grouping to simplify the equation. This is done by using like terms. To began ill break the equation into two groups.
i) (1)12x^3-60x^2
(2) 4x-20
ii) Now we look for like terms and simplify
(1) 12x^2(x-5)
(2) 4(x-5)
iii) Now we put them back as they were in the equation
12x^2(x-5) + 4(x-5)
iv) Now the x-5 factors out
we have (x-5)(12x^2+4)
Lasty, we simplify it to:
(x-5)4(3x^2+1) or 4(3x2 + 1)(x-5)
The last choice given in the answer bank.
Hope this helps, good luck.
The correct answer is C
(X-5)²+(Y-7)²=50
The answer of that question is a lot, idk
Answer:
A ; y = 2229-x
Step-by-step explanation:
The question is asking for us to find how many seats are left that can be sold. There are 2463 total seats, 234 reserved seats, and x non-reserved seats.
If we subtract the 234 reserved seats from total seats, we will get 2229, the number of non-reserved seats and the not sold seats.
Since x is the non-reserved seats, we can subtract x from 2229 to get the number of seats that aren't sold.
Rewrite it in the form a^2 - b^2, where a = 5x and b = 8
(5x)^2 - 8^2
Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)
<u>= C. (5x - 8)(5x + 8)</u>
