2x+2=nx-3
Answer:
the value of n that makes the equation have no solution is n = 2.
Step-by-step explanation:
To find the value of n that makes the equation have no solution, we can start by rearranging the equation in terms of x:
2x + 2 = nx - 3
Let's simplify the equation by combining like terms:
2x + 2 = nx - 3
Moving all the x terms to the left side and the constant terms to the right side, we get:
2x - nx = -3 - 2
Factoring out x on the left side:
x(2 - n) = -5
For this equation to have no solution, the coefficient of x (2 - n) must equal zero. This is because if the coefficient is zero, any value for x would result in the left side of the equation being zero, which would not be equal to the constant term on the right side (-5).
Setting 2 - n = 0, we can solve for n:
2 - n = 0
Subtracting 2 from both sides:
-n = -2
Multiplying both sides by -1 to isolate n:
n = 2
Therefore, the value of n that makes the equation have no solution is n = 2.

The surfacearea of the triangular pyramid is 242.039 square feet.
a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Area of equilateraltriangle = √(3)/4) x (side)²
= √(3)/4) x 13²
= 84.303 square feet
Now find the area of one of the triangular faces
Height² = (slant height)² - (base/2²
= 11² - (13/2)²
= 121 - 84.25
Height²= 36.75
Height = 6.063 feet
Area of triangular face = (1/2) x (base) x (height)
= (1/2) x 13 x 6.063
= 39.434 square feet
the total area of the triangular faces is:
4 x 39.434 = 157.736 square feet
Surface area = area of base + area of triangular faces
= 84.303 + 157.736
= 242.039 square feet
Hence, the surface area of the triangular pyramid is 242.039 square feet.
