Answer:
12x² - 2x - 30
Step-by-step explanation:
When multiplying binomials, remember to follow the FOIL method:
FOIL =
First
Outside
Inside
Last
Follow FOIL: (3x - 5)(4x + 6)
(3x)(4x) = 12x²
(3x)(6) = 18x
(-5)(4x) = -20x
(-5)(6) = -30
Combine like terms, simplify:
12x² + 18x - 20x - 30
12x² + (18x - 20x) - 30
12x² - 2x - 30
12x² - 2x - 30 is your answer.

Using the pythagorean theorem
A)
2 + 3 = 4
5 = 4
since 5 is not equal to 4 so A is wrong
B)
8 + 9 = 17
17 = 17
so answer B) is correct
C)
25 + 36 = 64
61 = 64
since 61 is not equal to 64 so C) is also wrong
