Answer:
14
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.
An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.
From the question:
KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)
From line segment addition postulate:
KV = KN + NV
substituting:
2x + 6 = 10 + x
2x + 6 - x = 10
x + 6 = 10
x = 10 - 6
x = 4
KV = 2x + 6
substituting x = 4:
KV = 2(4) + 6
KV = 14
Answer:
3x sqrt(2x)
Step-by-step explanation:
sqrt(6x^2) * sqrt(3x)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6x^2*3x)
sqrt(18x^3)
sqrt(9*2 x^2 x)
sqrt(a) sqrt(b) = sqrt(ab)
sqrt(9) sqrt(x^2) sqrt(2x)
3x sqrt(2x)
The answer is D and it's pretty simple to do:
