CB is equal to 10m you can tell this bye the side DC being 20 m and the angle of DC is half of CB so that means that CB has to be 10 m
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k = = = 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
Multiplying the linear expressions, the correct sequence is given as follows:
<h3>How are linear expressions multiplied?</h3>
They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.
Hence:
5x(-3 -7x)
(5x)(-3) + (5x)(-7x)
-15x - 35x²
Hence the last option is correct.

Hmmm, I think it sound more like the average. So mean. I'm not 100% sure but it isn't the median or the mode.
