The number could be any multiple of nine that ends in 4 or 9, like 9, 54, 99, 144, etc.
rate of change as in the gradient??
if yes then the formula would be rise over run, so y over x, therefore 1/3
Answer:
x=-22/3
Step-by-step explanation:
Answer:
4m, 4m, and 5 m
Step-by-step explanation:
From the information give;
- Two sides of a triangle are equal in length
- The third side is 3 m less than the common length
- Perimeter of the rectangle is 13 m
We are required to determine the dimensions of the triangle;
- Assuming the common sides are x m each
- Then, the third side will be (2x-3) m
- Perimeter of a triangle is equal to the sum of the lengths of the three sides
Therefore;
(2x-3) + x + x = 13 m
4x - 3 = 13m
4x = 16 m
x = 4 m
and, 2x-3 = 5 m
Therefore, the lengths of the three sides of the triangle are 4m, 4m, and 5 m
560 ft^2
20ft x 10ft = 200 ft^2
+
12ft x 30ft = 360 ft^2
=
560 ft^2
