I think the correct answer is option B. The system of equations given above will have only 1 solution. They will intersect only at 1 point when graphed in a x-y coordinate plane. Hope this answers the question. Please feel free to ask more questions.
Answer:
2L^2 - 27L + 70 = 0.
Step-by-step explanation:
p = 2(L + W)
27 = 2L + 2W
2W = 27 - 2L
W = (27 - 2L)/2
Substitute for W in the area equation:
A = LW
35 = (27 - 2L) * L / 2
L(27 - 2L) = 70
-2L^2 + 27L - 70 = 0 Multiply through by -1:
2L^2 - 27L + 70 = 0
The answer is 3√5 units

∠KMJ = 180° - 90° -adjacent angles on a straight line = 90°
Using Pythagora's Theorem
KJ² = 6² + 3²
KJ² = 45
KJ = √45
= √9√5
= 3√5
End point - points on either end of a line segment or on one end of a ray.
Ray - A part of a line, with one endpoint, that continues without end in one direction
Line - a line of points that extends infinitely in two directions
Collinear - points that lie on the same line
Midpoint - A point that divides a segment into two congruent segments
Plane - A flat surface on which a straight line joining any two points would wholly lie.
3 dimensions - height, width, and depth
Answer: A. scalene
<u>Step-by-step explanation:</u>
scalene = all three sides have different lengths
isosceles = two of the sides have the same length
equilateral = all three sides have the same length
AE = 5 <em>(2.5 + 2.5)</em>
ED = 3
AD = 7
Since all three sides have different lengths, it is a scalene triangle.
********************************************************************************
If it is a right triangle, then 3² + 5² = 7²
9 + 25 = 49
34 ≠ 49 <em>so it is not a right triangle</em>
