Find the missing side.

Vitek1552 [10]

Answer:

5

Step-by-step explanation:

This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.

Use the following formula to solve:

a² + b² = c²

In which:

a & b = shorter sides

c = hypotenuse

Plug in the corresponding numbers to the corresponding variables:

(3)² + (4)² = ?²

Solve. Remember to follow PEMDAS. First, solve the exponents, then add:

(3)² = (3 * 3) = (9)

(4)² = (4 * 4) = (16)

9 + 16 = ?²

25 = ?²

Isolate "?". Root both sides:

√(25) = √(?²)

? = √25 = √(5 * 5) = 5

Your missing side's measurement is 5.

Answer:

y = 12x - 9

Step-by-step explanation:

<u>Given</u>

- 1/3y + 4x = 3

Multiply all terms by -3

y - 12x = -9

Add 12x to both sides

y = 12x - 9

Simplify the expression.<br><br> (−5g5h6)2(g4h2)4

Colt1911 [192]

We have to simplify the expression here. The expression given,

$(-5g^5h^6)^2(g^4h^2)^4$

Now to find $(-5g^5h^6)^2$ we will use power of a product property. We have to distribute the power here. We will get,

$(-5g^5h^6)^2 = (-5)^2(g^5)^2(h^6)^2$

= $25(g^5)^2(h^6)^2$

Now we will use power of a power property. If given $(a^m)^n$ we will have to multtiply the powers and we will get $a^{mn}$ . So we will get here,

$25(g^5)^2(h^6)^2 = 25 g^{10} h^{12}$

Now the next part is $(g^4h^2)^4$

By using power of a power property we will get,

$(g^4)^4(h^2)^4 = g^{16}h^8$

Now we have to multiply them.

$(25g^{10}h^{12} )(g^{16}h^8)$

Now we have to use product of powers property. If we have same base them we will have to add the exponents there. The formula is $(a^m)(a^n) = a^{(m+n)}$ . So we will get here,

$25(g^{10} g^{16})(h^{12} h^{8})$

$25g^{(10+16)} h^{(12+8)}$

$25g^{26}h^{20}$

So we have got the required simplified answer here.

The simplified answer is $25g^{26}h^{20}$ .
