#1: Find the value of X. (GEOMETRY)

Mathematics
1 answer:
grandymaker [24]2 years ago
3 0

Answer:

x = 14

Step-by-step explanation:

1. We know that all angle measures in a triangle sum to 180 degrees.

  • This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.

2. (Solving)

Step 1: Combine like terms.

  • (7x+5x+2x)+(-11-2-3)=180
  • 14x -16 = 180

Step 2: Add 16 to both sides.

  • 14x - 16 + 16 = 180 + 16
  • 14x = 196

Step 3: Divide both sides by 14.

  • \frac{14x}{14}=\frac{196}{14}
  • x = 14

Step 2: Check if solution is correct.

  • 7(14)-11+5(14)-2+2(14)-3=180
  • 98-11+70-2+28-3=180
  • 180=180

Therefore, the answer is x = 14.

A rectangle has a length of (3x - 1) and a width of (x + 1). part a determine the perimeter and area of the rectangle as polynom
liubo4ka [24]

Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..

Lets try to solve out the problem,

Length = 3x-1

Width = x+1

Perimeter = 2(l+b)

Area = l*b

Perimeter= 2 (3x-1 + x+1)

P= 8x

Area = (3x-1) (x+1)

=> 3x(x+1) -1 (x+1)

=> 3x^2 + 3x -x -1

=> 3x^2 + 2x -1.

Hence Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..

What is the midpoint of a line segment with the endpoints (-4, -3) and (7, -5)
Katyanochek1 [597]
Midpoint Formula: (\frac{x+x}{2},\frac{y+y}{2})
Midpoint = (\frac {-4+7}{2},\frac {-3-5}{2})
Midpoint = (\frac {3}{2},\frac {-8}{2})
Midpoint = (\frac {3}{2}, -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is (\frac {3}{2}, -4).
