16x^2 - 64 = 0

16x^2 = 64

x^2 = 64/16

x^2 = 4

sqrt{x^2} = sqrt{4}

x = -2, x = 2

Answer: B and F

Answer:

B and F

2, -2

Step-by-step explanation:

16x^{2} -64=0

Add 64 to both sides.

16x^{2} -64+64=0+64

Simplify

16x^{2} =64

Divide both sides by 16.

\frac{16x^{2} }{16} =\frac{64}{16}

Simplify

x^{2} =4

x=\sqrt{4} ,-\sqrt{4}

Simplify

x=2,-2

What is the value of v?<br> 1 / 4 (v – 7) = 2
belka [17]
1/4 (v - 7) = 2

1/4v - 1/4 (7/1) = 2

1/4v - 7/4 = 2

1/4v = 15/4

Multiply by 4/1 on both sides to get v

(4/1) 1/4v = 15/4 (4/1)

v = 60/4

v = 15

If tanA+sinA=m and tanA-sinA=n.prove that m^2-n^2=4√mn
mash [69]

Let a=\tan A and b=\sin A. Then

m^2-n^2=(a+b)^2-(a-b)^2=(a^2+2ab+b^2)-(a^2-2ab+b^2)=4ab

\implies m^2-n^2=4\tan A\sin A

and

mn=(a+b)(a-b)=a^2-b^2

\implies4\sqrt{mn}=4\sqrt{\tan^2A-\sin^2A}

The expression under the square root can be rewritten as

\tan^2A-\sin^2A=\dfrac{\sin^2A}{\cos^2A}-\sin^2A=\sin^2A\left(\dfrac1{\cos^2A}-1\right)=\sin^2A(\sec^2A-1)

Recall that

\sin^2A+\cos^2A=1\implies\tan^2A+1=\sec^2A

so that

\tan^2A-\sin^2A=\sin^2A\tan^2A

and assuming \sin A>0 and \tan A>0, we end up with

4\sqrt{\tan^2A-\sin^2A}=4\tan A\sin A

so that

m^2-n^2=4\sqrt{mn}

as required.

Simplify the expression 10-4x(6+5-1) divided by 8+7
Eddi Din [679]
Simple,

writing out the problem...

\frac{10-4x(6+5-1)}{15}

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

\frac{10-40x}{15}

Cancel out the common factors...

Thus making the answer:

- \frac{2(4x-1)}{3}.
