Answer:
x = 6
Step-by-step explanation:
Given that Δ JKL is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x, that is
13x + 5 = 8x + 35 ( subtract 8x from both sides )
5x + 5 = 35 ( subtract 5 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
An equilateral triangle is a triangle where all three sides are equal.
The value of x is 6.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
An equilateral triangle is a triangle where all three sides are equal.
∆JKL is an equilateral triangle.
JK = 13x + 5
KL = 17x – 19
JL = 8x + 35
Now,
JK = 13x + 5
KL = 17x – 19
JK = KL
13x + 5 = 17x - 19
5 + 19 = 17x - 13x
24 = 4x
x = 6
Thus,
The value of x is 6.

There are 4 consecutive integers that have a sum of 338. What is the least of these integers?
Answer:
The least of the four integers is 83.
Step-by-step explanation:
Let x be the first integer.
x + (x + 1) + (x + 2) + (x + 3) = 338
4x + 6 = 338
4x = 332
x = 83
83 + 84 + 85 + 86 = 338

What is an equation in point-slope form of the line that passes through (-7,1) and (-3, 9)
Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J
Answer:
The correct option is;
C. 4800 J
Step-by-step explanation:
The given parameters are;
The mass of the skier = 40 kg
The height of the slope = 12 meter
The acceleration due to gravity, g = 10 m/s²
The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h
Substituting the values, gives
The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J
The potential energy, PE = 4800 J
