It will take 1/2 an hour because if 1/2 of a wall is painted with 1/4 of an hour, then we know if you want the other half, you have to add another 1/4 of an hour which is 2/4.
2/4 is equivalent to 1/2 so 1\2 of an hour is how long it will take.

B and f should be correct
I’m literally bad at rounding but uh for the total volume of both shapes added together its 37.68
Answer:
The answer is B: ( g o f) (x) = ( x + 1)^2
Explanation:
⟹ (g ∘ f) (x) = g [f (x)]
Replace x in g(x) = x^2 with x+1
= ( x + 1 ) ^2
Answer:
Perpendicular
Step-by-step explanation:
First note:
- Parallel lines have equal slope
- Perpendicular lines have slopes that are negative reciprocal to each other
Lets check, first we need to convert them to slope intercept form (y = mx + b), where m would be the slope.
L1:
4x + 5y = 15
5y = -4x + 15
y = -4/5x + 3
L2:
4y = 5x - 12
y = 5/4x - 3
Slope of L1 is -4/5 and Slope of L2 is 5/4
<em>Are they negative reciprocals of each other? Yes, because multiplying the slopes would give us "-1"</em>

So the lines are Perpendicular
