The perimeter of the triangle ABC is 10+\sqrt{10} units.

The given parameters:

  • <em>Triangle ABC = Isosceles triangle</em>

The length of AC = 3-(-2) = 5 unit

The length of AC = length of BC = 5 unit

The length of BC is calculated by applying Pythagoras theorem as follows;

BC^2=(4-1)^2+(3-2)^2

BC^2=3^2+1^2

BC^2=10

BC=\sqrt{10}

The perimeter of the triangle ABC is calculated as follows;

P=AB+AC+BC

P=5+5+\sqrt{10}

P=10+\sqrt{10  units

Solve the following inequality for y.<br> 18x + 6y &gt; 12
Murljashka [212]

Answer:

12

Step-by-step explanation:

Simplifying

18x + -6y = 12

Solving

18x + -6y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

18x + -6y + 6y = 12 + 6y

Combine like terms: -6y + 6y = 0

18x + 0 = 12 + 6y

18x = 12 + 6y

Divide each side by '18'.

x = 0.6666666667 + 0.3333333333y

Simplifying

x = 0.6666666667 + 0.3333333333y

Find the area of a rectangle that has a length of 5x+1 and a width of 2x+3
pantera1 [17]
I could be wrong, but I'm pretty sure here the answer would be 10x^2 + 17x +3 would be the area since you have to multiply length and width. since these are expressions with no answers and no other numbers, we can't find x.
