X^2-3x-7x+16=0
x^2-10x+16=0
(x-8)(x-2)=0
x=8 or x=2
Let y represent the total weight of mulch and x represent the number of bags of mulch, then
y = kx.
Rate of change (k) = y/x. i.e. the weight of mulch divided by the number of bags.
Answer:
99 square units
Step-by-step explanation:
We are given;
- a polygon Y whose area is 11 square units
- The scale factor which it was drawn to become polygon Z is 3
We are required to determine the area of polygon Z
We need to know that;
Area scale factor = Square of Linear scale factor
That is;
Area scale factor = 3²
= 9
Hence;
Area of polygon Z = Area of polygon Y × Area scale factor
= 11 square units × 9
= 99 square units
Thus, the area of polygon Z is 99 square units
