Answer:
see explanation
Step-by-step explanation:
Note that (x² + 5)(x² - 5) are the factors of a difference of squares
a² - b² = (a + b)(a - b)
with a = x² and b = 5, hence
(x² + 5)(x² - 5) = (x²)² - 5² = 
- 25, thus
3( - 25) = 3 - 75
Perpendicular is the answer because for it to be perpendicular it has to be the opposite 3/4’s opposite is -4/3 which is why the answer is perpendicular
"15/45" = "1/3"
"45/135" = "1/3"
Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
Answer:
y=4
Step-by-step explanation:
Because it is a horizontal line, there is no slope the only thing that is there is the y intercept
