Answer:
26x³ - 12x² + 5x + 7
Step-by-step explanation:
- (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
- 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
- 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
- 26x³ + 5x + 7 - 12x²
= 26x³ - 12x² + 5x + 7

Answer:
(x -4)^2 +(y +5)^2 = 2
Step-by-step explanation:
The equation of a circle centered at (h, k) through point (p, q) is ...
(x -h)^2 +(y -k)^2 = (p -h)^2 +(q -k)^2
Filling in your given numbers gives ...
(x -4)^2 +(y +5)^2 = (5-4)^2 +(-4+5)^2
(x -4)^2 +(y -5)^2 = 2
The correct answer is: D) Subtracted like terms incorrectly
Step-by-step explanation:
Given

The terms 11.2y-7.4y need to be subtracted. But option b is to add them. We will add them and then solve the equation to see if its right.
So adding 11.2y-7.4y

Dividing both sides by 18.6

so by adding the terms instead of subtracting we get y=7.6.
this means that the error was adding 7.4y-11.2y instead of subtracting
The correct method will be:

Dividing both sides by 3.8

Hence,
The correct answer is: D) Subtracted like terms incorrectly
