Answer:

4x²+17x-15

Use the FOIL method. Multiply the first term in each group, then the outer ones, then the inner ones, and finally the last term in each group together. The first terms in this case are 4x and x, the outer terms are 4x and 5, the inner terms are -3 and x, and the last terms are -3 and 5.

Hope this helps!

What is the sum of the measures of the interior angles of a hexagon?
Eduardwww [97]

Answer:

720°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 ( number of sides of a hexagon ), thus

sum = 180° × 4 = 720°

The picture below shows a right-triangle-shaped charging stand for a gaming system:
Setler79 [48]

This question is incomplete because it lacks the diagram of the right angles shaped charging stand.

Find attached to this answer, the appropriate diagram.

Answer:

3(tan 50°)

Step-by-step explanation:

To solve this question, we would be using the Trigonometric function called Tangent.

tan θ = opposite side/ adjacent side

θ = 50°

Opposite side (Height)= Side AC = Unknown

Adjacent side = Side BC = 3 inches

Hence,

tan 50° = Side AC/ Side BC

tan 50° = Side AC / 3

Cross multiply

tan 50° × 3 = Side AC

3(tan 50°) = Side AC

Therefore, the expression shows the height, AC, of the charging stand is

3(tan 50°).
