6x^3 a negative times a negative cancels out making it positive
Answer:
An expression for this would be 3y as length * breadth is the area of a rectangle.
substitute 3 in X's place
-2x + 5 = -2(3) + 5 = -6 + 5 = -1
hope it helps...!!!
X= 4-2
X= 6-4
X = 8-6
Is this what u want?
Answer:
A. x = 5 (Equation below)
B. AC = 9 | BD = 9
Step-by-step explanation:
A. Since we know the diagonals of an isosceles trapezoid are congruent, we know that the two bottom parts of the diagonal BD (2x - 8 and x - 4) are congruent to the diagonal AC (x + 2) . This means you can just equal them together and get the value of x:
2x - 8 + x - 4 = x + 2
3x - 12 = x + 2
3x = x + 14
2x = 14
x = 7
B. Just plug in 5 for x:
AC = x + 2 = 7 + 2 = 9
BD = 2x - 8 + x -4 = 3x - 12 = 21 - 12 = 9
