A^{-1} = \frac{1}{/A/} * Adj A

Step-by-step explanation:

A^{-1} = \frac{1}{/A/} * Adj A

Answer:

<h2>: 7-⁴</h2>

Step-by-step explanation:

<h3>Exponential Form :</h3><h3>(a^m*a^n ) = (a^m+n )</h3>

<h3>7^-6 = 7^-2 * x </h3>

<h3>(only 7^-4 the term that can add to 7^-2 gives </h3><h3>= 7^-6 )</h3>

<h3>7^-6 = 7^-2 + 7^-4 </h3>

<h3> ( a^m*a^n) = ( a^m+n)</h3>

The longest side in a right triangle is 24 cm, and the second longest side is 20 cm. Find the length of the shortest side
harkovskaia [24]

Answer:

13.3 cm

Step-by-step explanation:

Apply the Pythagorean Theorem:

hyp² = (2nd longest side)² + (shortest side)².  Here the numbers are:

(24 cm)² = (20 cm)² + (shortest side)², or

576 - 400 = 176 = hyp²

Taking the square root of both sides, we get (shortest side) = 13.3 cm

Evaluate z + 2+ z for x = 2, y=-3, z = -4.
Artyom0805 [142]

Answer:

-6

Step-by-step explanation:

Are you sure that z + 2+ z is correct?  x and y do not appear here.

z + 2+ z simplifies to 2z + 2, and so, if z = -4, z + 2+ z has the value

2(-4) + 2, or -6.
