The lengths, in cm, of the sides of a triangle are 3x – 5, 2x – 1 and x + 1 (a) Write down an expression, in terms of x, for the perimeter of the triangle.

Answers

Answer: [tex]6x-5[/tex]

Step-by-step explanation:

Given

The side lengths of a triangle are  [tex]3x-5, 2x-1,\text{and}\ x+1[/tex]

Perimeter(P) is the sum of the side length of the triangle i.e.

[tex]\Rightarrow P=3x-5+2x-1+x+1\\\Rightarrow P=6x-5[/tex]

Therefore, the perimeter of the triangle is [tex]6x-5[/tex]

Find the length of each arc. Use the exact answer

Answers

Answer:

Option D = 16π/3 ft

Step-by-step explanation:

Arc length formula is written Mathematically as:

Arc length = 2πr × θ /360

r = 4 ft

θ = Central angle in degrees = 240°

2 × π × 4 × 240/360

8π × 240/360

8π × 20/30

16π/3 ft

So, the arc length is 16π/3 ft

Solve for the value of x in the following parallelograms.

Helppp, thanksss:)​

Answers

1) combined total of the degrees should be 360. Opposite angles are congruent. So if one angle is 80 so is the one opposite it. 360-160=200
Then divide by two because u need to find x which is one angle. X is 100
2) opposite sides are congruent so you set them equal.
31=2x-5
-5 -5
26=2x
/2 /2
13=x
3) you set them equal because opposite angles are congruent
x+3=4x-27
-x -x
3=3x-27
+27 +27
30=3x
/3 /3
10 = x

Answers

Answer:

Use coordinates of the vertices and the slope formula.

H(-3, 0), E(1, 4), F(3, 2), G(-1, -2)

1. Slope of HE:

m = (4 - 0)/(1 + 3) = 1

2. Slope of GF:

m = (-2 - 2)/(-1 - 3) = 1

3. Slope of HG:

m = (-2 - 0)/(-1 + 3) = -1

4. Slope of EF:

m = (2 - 4)/(3 - 1) = -1
