Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
The answer is (z - 3) (w + 6)
Answer:
164 (We can use rounding techniques)
Note: If you need futher help on this, there are many online tools that you can use. Also, you can ask your teacher(s) or parents if you need help.
We know that a supplementary angle is equal to 180. Since we have one angle, we can easily find the other angle.
180 - 128.9 = 51.1
The other angle is equal to 51.1 degrees
Answer:
a+b>c
a+c>b
b+c>a

1. Learn the triangle inequality theorem.
This theorem simply states that the sum of two sides of a triangle must be greater than the third side.
