Answer: Choise A and Choise B.

Step-by-step explanation:

Given the following expression:

3x+3(x+y)

You can simplify it in order to find equivalent expressions.

Appying the Distributive Property, you get:

3x+(3)(x)+(y)(3)=3x+3x+3y

So:

1. If you add the like terms, you get this equivalent expression:

3x+3x+3y=6x+3y

2. But if you factor out 3, you get the following equivalent expression:

3x+3x+3y=3(x+x+y)

Therefore, the expression shown in Choice A and Choise B are equivalents to the expression 3x+3(x+y)

The middle school basketball team is selling t-shirts for $12.50 each to raise money for new uniforms. They have already sold 40
Rama09 [41]

Step-by-step explanation:

given:

$12.50- the price of the tshirts

40- the tshirts they have sold

$850- the raise they need

solve:

$12.50 × 40 = $500 (the price of tshirts and tshirts they have sold)

$850 - $500 = $350 (the raise they need and the money they have so far from the 40 tshirts they have sold)

$350 ÷ $12.50 = 28 (the money they lack and the price of a tshirt)

answer:

thus, they need to sell 28 more tshirts to have the raise of at least $850

hope this helps, good luck! :)

If tan theta = startfraction 11 over 60 endfraction, what is the value of cot theta?
Dennis_Churaev [7]

The value of cot\theta when tan\theta =\frac{11}{60} comes to be \frac{60}{11}.

Given that trigonometric ratio:

tan\theta = \frac{11}{60}

<h3>What is the tangent of an angle?</h3>

The tangent of an angle is the ratio of the opposite side(to that angle) to the adjacent side(to that angle).

So, for the given problem

Opposite side to \theta = 11

Adjacent side to \theta = 60

So, cot \theta =\frac{AdjacentSide }{OppositeSide}

cot\theta =\frac{60}{11}

Therefore, the value of cot\theta when tan\theta =\frac{11}{60} comes to be \frac{60}{11}.

Answer:

since it's the lhs we are concerned about, i. e., Y axis, so it must be either up or down. now look at the question, it says 8x2 - (1), it means one lower value of y i. e., 1 unit down
