Answer:
<h3>ya-z/1+y</h3>
Step-by-step explanation:
Making x the subject of the formula;
y=x+z/a-x
Cross multiply
y(a-x) = x+z
ya - yx = x+z
Collect like terms
x+yx = ya - z
x(1+y) = ya - z
x = ya-z/1+y
Hence the value of x is ya-z/1+y
Translation of a line segment doesn't affect it's length, 'cause it has shifted from one location to another, no change in it's size.
In short, Your Answer would be Option B
Hope this helps!
The area of a rectangle is length times width or base times height
so 5 times 2x-3
if you multiply them together 5(2x-3) you would get 10x-15
there is no value of x
so the area would be 10x-15ft^2
