Answer:
(D)Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals
Step-by-step explanation:
To use coordinate geometry to prove that quadrilateral ABCD is a rectangle. We prove that opposite sides are congruent in order to show equality of the lines.
We also show that the slopes of consecutive sides are opposite reciprocals, this is in order to show that the lines are perpendicular to one another.
<u>The correct option is D.</u>
Answer:
a = 3
Step-by-step explanation:
-12x³+14x²+6x = -2x(ax+1)(2x-3)
<em>Divide both sides by -2x(2x-3)</em>
ax+1=3x+1
<em>Subtract 1 from both sides</em>
ax=3x
<em>Divide both sides by x</em>
a=3
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
