Answer:

x=5

Step-by-step explanation:

Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:

x^2-7=4x-2

x^2-4x-5=0

(x-5)(x+1)=0

x=5,-1

Since a side of a triangle can't be negative, the answer is 5.

Find the midpoint of the segment below and enter its coordinates as an
Sati [7]

Answer:

(-1/2,5)

Step-by-step explanation:

Here is the complete question

Find the midpoint of the segment with endpoints of (1, 4) and (-2, 6) and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

Solution

The mid-point of a line is given by ((x₁ + x₂)/2,(y₁ + y₂)/2). From the question, x₁ = 1, y₁ = 4, x₂ = -2 and y₂ = 6. So,

((x₁ + x₂)/2,(y₁ + y₂)/2) = ((1 + (-2))/2,(4 + 6)/2)

                                  = ((1 - 2)/2,10/2)

                                  = (-1/2,10/2)

                                  = (-1/2,5)

yulyashka [42]

Answer:

The probability is 3/5

Step-by-step explanation:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

There are 2 + 4 + 4 + 4 + 2 + 4 = 20 itens.

Of those, 2 + 4 + 2 + 4 = 12 itens have white or red.

So

12/20 = 3/5
