Answer:

6a+4b-14

Step-by-step explanation:

Distributive property. Multiply everything in the parenthesis by the number outside.

So you get

2 times 3a = 6a

2 times 2b = 4b

2 times-7 = -14

If sin theta = 2/7 and tan theta>0 what is the value of cos theta
Ronch [10]

Answer:

Step-by-step explanation:

sin(θ) = 2/7

sin²(θ) +cos²(θ) =1

(\frac{2}{7})^{2} +cos^2(theta)=1 \\\\cos^2(theta)=1-(\frac{4}{49} )=\frac{49}{49}-\frac{4}{49} =\frac{45}{49} \\ \\cos(theta)=+/-\sqrt{\frac{45}{49} } =+/-\frac{3\sqrt{5} }{7}

Answer \\ is \frac{3\sqrt{5} }{7}

Answer is positive because tangent is positive, sin is also positive, and tan=sin/cos.
