Answer:

AB = 5

Step-by-step explanation:

Because it is an isosceles triangle, we can say that AB equals BC, so we can form an equation.

AB = BC

3x - 4 = 5x - 10

→ Minus 5x from both sides to get the 'x' on one side

-2x - 4 = -10

→ Add  -4 to both sides to isolate -2x

-2x = -6

→ Divide both sides by -2 to isolate x

x = 3

Now we know that x = 3, we can put it in to the length of AB

3 × 3 - 4 = 9 - 4 = 5

Answer:

AB = 5

Step-by-step explanation:

Since the triangle is isosceles then the legs are congruent, that is

BC = BA, substitute values

5x - 10 = 3x - 4 ( subtract 3x from both sides )

2x - 10 = - 4 ( add 10 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Thus

AB = 3x - 4 = 3(3) - 4 = 9 - 4 = 5

Write an expression in simplest form that represents the perimeter of the polygon ​
scoundrel [369]

Answer:

Perimeter = (11x + 12)

Step-by-step explanation:

Since, perimeter of a polygon is represented by the sum of measures of all sides,

Perimeter of the given polygon = 3x + (x + 10) + 5x + (2x + 2)

By adding like terms of the expression,

Perimeter of the polygon = (3x + x + 5x + 2x) + (10 + 2)

                                          = (11x + 12)

Therefore, expression for the perimeter is (11x + 12).

Answer:

They will be able to.

Step-by-step explanation:

You first want to make sure the first three families have enough to eat.

6\frac{1}{2} - 2\frac{7}{8} = 3\frac{5}{8}

For further explanation look at the first image.

3\frac{5}{8} > 2\frac{7}{8}

Just to make sure

3\frac{5}{8} - 2\frac{7}{8}=\frac{3}{4}

For further explanation look at the second image.

The rest of the images show a model solution.
