X^2 + x^2=6^2 what is x​
nikitadnepr [17]

Answer:

x = ±3 sqrt(2)

Step-by-step explanation:

x^2 + x^2=6^2

Combine like terms

2x^2 = 6^2

Divide each side by 2

x^2 = * 6^2/2

Take the square root of each side

sqrt(x^2) =± sqrt(  6^2/2)

Remember that sqrt(a/b) = ±sqrt(a ) /sqrt(b)

x = ±sqrt(6^2)/sqrt(2)

x = ±6 /sqrt(2)

We do not leave square roots in the denominator, so we multiply the top and bottom by sqrt(2)

x = ±6 /sqrt(2) * sqrt(2)/ sqrt(2)

x = ±6 *sqrt(2) /( sqrt(2)*sqrt(2))

x =  ±6 sqrt(2) /(2)

x = ±3 sqrt(2)

18+6/-4-16 HELP only d part​
Ivahew [28]

Answer:

\frac{1}{2} is the answer

Step-by-step explanation:

First we need to substitute X and Y with their respective numbers

3\cdot \:6+\frac{6}{-4}-\left(-4\right)^2

Then, following PEMDAS, We just need to simplify

18+\frac{6}{-4} -16

16.5-16=0.5=\frac{1}{2}

Find the value of x picture attached
aev [14]

Answer:

<em>x = 10</em>

Step-by-step explanation:

These angles are <em>same side interior angles</em>.

This means that (11x + 10) + (10x - 40) = 180

Solve for x:

11x + 10 + 10x - 40 = 180

21x - 30 = 180

      +30     +30

21x = 210

/21      /21

<em>x = 10</em>

1+sec^2xsin^2x=sec^2x
Sholpan [36]
1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1
