The sum of length and width of a rectangle is half the perimeter. Here the sum of length and width is 114/2 = 57 ft.
If we add 12 ft to this total, we have a value that is 3 times the width.
The width of the sign is 69 ft/3 = 23 ft.
The length of the sign is (2·23 -12) = 34 ft.
_____
From the problem statement, using L and W for length and width:
... L = 2W -12
... P = 114 = 2(L +W)
Dividing the second equation by 2 and substituting for L, we have ...
... 57 = (2W -12) +W
... 69 = 3W . . . . . . . . add 12
... 23 = W . . . . . . . . . divide by 3
Answer:
A, C and F
Step-by-step explanation:
According to exponent laws:
Therefore F needs to be checked
this can further be simplified into:
we square the denominator and numerator
therefore C should be checked
if we expand it will also look like :
so A should be checked
Answer:
The answer is "5, 12, and 13".
Step-by-step explanation:
Please find the complete question in the attached file.
The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.
The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:
And even those squares do verify the equation:
So, it's a rectangular (right) triangle, with sides spanning
