Answer:
w = 3x+8/h
Step-by-step explanation:
area rectangle w×h×l (w : weight, h : height, l : length )
18x + 24 = 6×w×h ➡ w×h = 3x + 8
Answer:
y = 
- 8
y = -
+ 3
y = 
- 8
y = 
Step-by-step explanation:
To know the pairs that are perpendicular lines, we need to understand what makes a line perpendicular to another.
Perpendicular lines generally have slopes;
m and 
So, any of the pairs with a negative inverse value of slope will be perpendicular.
y = - 8 slope = 
y = 
slope = 
We see they are negative inverses
y = - 8 slope = 
y = slope = 
These are also negative inverses.

5 times 8 =40
Answer:
DB = 6
Step-by-step explanation:
See the attached figure to the question.
Since O is the center of the given circle, so AB and CD are diameters of the circle.
Hence, AO = CO = OD = OB = radius of the circle = 6
In Δ OAC, we have AO = OC. Hence, ∠ A = ∠C = 60° {Given that ∠OAC = 60°}
So, ∠ AOC will automatically become 60°. {As the sum of all the angles of a triangle is 180°}
So, Δ AOC is equilateral triangle.
Now, ∠ AOC = ∠ BOD = 60° {Since, they are vertically opposite angles}
Now, in Δ BOD, we have DO = OB. Hence, ∠ D = ∠ B = 60° {As the sum of all the angles of a triangle is 180°}
So, Δ BOD is also an equilateral triangle.
So, DB = BO = DO = 6. (Answer)
