To find CD use the trig ratio that relates that side you're looking for to the angle you have and the other side you're given.  We have that the reference angle is 30, and we also have the hypotenuse of that right triangle on the left.  Solving for AC, which is the side opposite, we will use the sin ratio: sin(30)= \frac{AC}{10}.  10 sin(30) = AC.  Therefore, AC = 5.  Now that have that side measure, we can use that along with the reference angle in the right triangle on the right of 25 to find CD, which happens to be the side adjacent to the reference angle.  That satisfies our tangent ratio requirements.  Our ratio looks like this then: tan(25)= \frac{5}{CD}.  Solving for CD, CD= \frac{5}{tan(25)} and CD = 10.7, the third choice above.

Which expression represents the product of negative three-fourths x and –8x? negative 35 over 4 x 6x negative 35 over 4 x square
valentinak56 [21]

The expression that represents the product of negative three-fourths x and –8x is 6x^2

<h3>How to determine the equivalent expression?</h3>

The statement is given as:

the product of negative three-fourths x and –8x

Rewrite properly as:

-3x/4 * -8x

Divide 4 and 8 by 4

-3x * -2x

Multiply -3 and -2

6x * x

Multiply x and x

6x^2

Hence, the expression that represents the product of negative three-fourths x and –8x is 6x^2

Your basketball team scored 4 fewer than twice as many points, x, as the other team. a. Write an expression for the number of po
velikii [3]

Answer:

A) p = 2x - 4  for the expression. B) Your team scored 44 points.

Step-by-step explanation:

Let <u>P</u> represent the points your team made.

Since the question says "Your basketball team scored 4 fewer than twice as many points as the other team." this is how I came up with the expression.

p = 2x - 4 ( our points = 2 times more then the other teams points minus 4.

Using this expression and the given information that the other team made 24 points, I solved B.

44 = 2(24) - 4.
