Using Pythagorean theorem, the answer should be D
Answer: 8x⁴ - 12x³ - 176x² + 420x
Step-by-step explanation:
First multiply 4x by (x - 3) which = 4x² - 12x. Next multiply (4x² - 12x) by (x + 5) which = 4x³ + 8x² - 60x. Multilying our new trinomial with the next binomial: (4x³ + 8x² - 60x)(2x - 7) = 8x⁴ + 16x³ - 120x² - 28x³ - 56x² + 420x. Combining like terms: 8x⁴ - 12x³ - 176x² + 420x. Notice that when you reduce and factor, you will end up with the starting binomials meaning this solution is correct.

Answer:
Subtract 5x from both sides of the equation
-3y = 12 - 5x
Then, divide each term by -3 and simplify.
y = -4 + 5x
------
3
After that, you'll do this
y= 5x
----- - 4
3
Lastly, you put that into slope-intercept form.
y = 5
---- x - 4
3
Well the answer would be 120=120 and 68=68
