(a) The sum of length and width is half the perimeter, so the breadth in terms of length (x) in cm will be
.. breadth = 34 -x
(b) Then the expression for the area (in cm^2) is
.. area = length*breadth
.. 253 = (x)(34 -x)
.. x^2 -34x +253 = 0 . . . . . subtract the right side, eliminate parentheses
.. (x -11)(x -23) = 0 . . . . . . . factor
.. x = 11 or 23
The dimensions of the rectangle are 11 cm by 23 cm.
Answer:
E = $385
Step-by-step explanation:
35 x 11 = 385
Answer: 
Step-by-step explanation:
By the Intersecting Secants Theorem, we know that:
Having this, we can find the value of "x" by solving for "x":
Applying Distributive property:
Subtract 25 from both sides of the equation:
And finally dviding both sides of the equation by 5, we get:
Tree A grew slower.
4.15 is less than 4.2 and Tree A is growing at the “lesser” rate, making it the slower growing tree.
Subtract Evans scores from the mean:
X = 138 - 125 = 14
Y = 138 - 137 = 1
Subtract the mean from the score because the score is higher this time:
Z = 145 - 138 = 7
