Use the Distributive Property to expand -3 (8x - 4).

Answers

Answer 1

Answer: -3(8x-4). With D property, that would be
-24x + 12

Answer 2

Answer:

Final answer:

The Distributive Property is applied to -3(8x - 4) by multiplying -3 by each term inside the parenthesis, which gives the expanded form -24x + 12.

Explanation:

To use the Distributive Property to expand -3(8x - 4), you need to multiply each term inside the parenthesis by -3.

Multiply -3 by 8x: -3 × 8x equals -24x
Multiply -3 by -4: -3 × -4 gives +12, because when two negative numbers are multiplied, the answer has a positive sign.

Now combine the two products you obtained:

-24x + 12

Therefore, the expanded form of -3(8x - 4) using the Distributive Property is -24x + 12.

Polygon ABCD will be dilated by a factor of 2 to produce polygon A′B′C′D′. The origin is the center of dilation. Which point will not represent a vertex on polygon A′B′C′D′ ? (-2, -2) (4, 3) (0, 2) (4, -2)

Answers

Since the origin is the center of dilation then the factor of dilation is 2 so just multiply the coordinate of every vertex by 2. So, the vertices will become A'(-2,-2), B'(0, 2), C'(4, 4) ad D'(4,-2). Therefore, letter B is the answer.

Dr. Black is standing 13 feet from a streetlamp. The lamp is making his shadow 9 feet long. He estimates that the angle of elevation from the tip of his shadow to the top of the streetlamp is 50. To the nearest foot, the streetlamp is about _____.

Answers

Distance from tip of shadow to lamp post = 13 +9 feet = 22 ft Height of lamp post = x tan 50 = x /22 = 1.192 x = 22 * 1.192 =.26.2 ft. rounded = 26ft

Answer:

26 ft height

Step-by-step explanation:

The distance between the streetlamp and the tip of his shadow is 9 + 13 = 22 ft.

A rectangle triangle is formed in which one side is 22 ft long and the other side is the streetlamp height. The angle between the 22 ft side and the hypotenuse is 50°. From tangent definition:

tan(50°) = (streetlamp height)/(22 ft)

tan(50°) * (22 ft) = streetlamp height

26 ft = streetlamp height
