Answer: 7
Step-by-step explanation:
f(x) = y
f(-5) = y
x = -5
find the value of y at x = -5
and the answer is 7
Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
