This one is A.  Since the coin was removed from the coin purse, the number of coins changed.  So the probabilities also changed.

Can someone help it has to be a polynomial
Damm [24]

Answer: Width = 24 inches

Step-by-step explanation:

Let W represent the width of the rectangular sign.

The length of a rectangular sign is 6 inches more than half its width. It means that the length of the rectangular sign would be

W/2 + 6

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of the sign is 432 square inches. Therefore, the equation for the area of this sign would be

W(W/2 + 6) = 432

W²/2 + 6W = 432

Multiplying both sides of the equation by 2, it becomes

W² + 12W = 864

W² + 12W - 864 = 0

W² + 36W - 24W - 864 = 0

W(W + 36) - 24(W + 36) = 0

W - 24 = 0 or W + 36 = 0

W = 24 or W = - 36

Since W cannot be negative, then

W = 24

A tangent-tangent angle intercepts two arcs that measure 124 degrees and 236 degrees what is the measure of the tangent-tangent
andrezito [222]

Answer:

It can be calculated by finding the difference between the two angles. Half of this difference will be the angle that is required.

Therefore

236 - 124 = 112

Tanget-tanget angle = 112 / 2 = 56 degrees

The rectangles below are similar in shape. How wide is the smaller rectangle?
Amanda [17]

Answer:

\huge\boxed{x=28\ ft}

Step-by-step explanation:

If two rectangles are similar, then corresponding sides are in proportion.

Therefore we have the equation:

\dfrac{x}{42}=\dfrac{36}{54}

cross multiply

54x=(42)(36)\\\\54x=1512

divide both sides by 54

\dfrac{54x}{54}=\dfrac{15212}{54}\\\\x=28
