Step-by-step explanation:
(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x + 5 ⇒ m = 
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
= - 
y =
x + 4 ⇒ m = 
y = -
x + 5 ⇒ m = - 
y =
x + 3 ⇒ m = 
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
= - 
the 2nd and 4th lines are perpendicular
Answer:
-15 and 1
Step-by-step explanation:
The answer would be 13.546
you would do 162.56 divided by 12.
1. True.
2. False. x² + 4 = (x+2)(x-2)
3. True.
4. False. It gives (x²-9) which is a binomial.

The volume of a cylinder is given by πr²h
r= x-3, while h =2x+7
Thus; volume = π(x-3)²(2x+7)
=π(x²-6x+9)(2x+7)
=π( 2x³-12x²+18x +7x²-42x+63
= π(2x³-5x²+24x+63) cubic units
