3x+2x= 5x
Sorry, I cant understand what the second line means, hopefully this helped:)
The slope of the line is the dy/dx value every time it appears in the differential equation. By substituting values for x and y in the DE, the slope can be found for the tangent at a point. This is the value of m in y=mx+a. To find a, plug in the tangent point.
Answer:
$109.71
Step-by-step explanation:
first we find the perimeter
=2(280+200)
=2×480
=960m
now we multiply it by 4 as he wants it 4 times around
960×4
3840
now we find the fencing cost
since 35 per meter we divide it by 35
3840/35
=$<u>109.71</u>
