A trapezoid with legs MN = FD is an isosceles trapezoid.
An isosceles trapezoid has diagonals that are congruent, therefore: MF = ND.
A quadrilateral with diagonals congruent and perpendicular is a square.
In a square, the height coincides with the side.
The area of a square is given by A = s²
Therefore, the area of MNFD is h²
Answer: 4(x + 9) = 3x − 8 − 5
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
4(x + 9) + 5 = 3x − 8
The subtraction property of equality states that if we subtract the same number from both sides of the equation, the equality remains.
So, if we subtract 5 from both sides:
4(x + 9) + 5-5 = 3x − 8 -5
4(x + 9) = 3x − 8 − 5
Feel free to ask for more if needed or if you did not understand something.
Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
