Can someone help
me with question C a and b? Please provide an explanation if
you can I’m really stuck

Step-by-step explanation:

It ain't that hard. Let's take the first one:

y = 4x + 2z

If you wanna make x the subject, you try to get rid of anything by its side. In other words:

Everything boils down to 2 easy steps:

Now let's check the second example:

That's it :)

If you have any questions please feal free to ask

b is the answer that makes most sense

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
