Answer:

AB = 25 units

Step-by-step explanation:

In right triangle ACB, $CD\perp AB$

Therefore, by geometric mean property:

$CD^{2} ={AD\times DB} \\ \\ {10}^{2} = AD\times 5 \\ \\ 100 = 5AD \\ \\ AD = \frac{100}{5} \\ \\ AD = 20$

AB = AD + DB

AB = 20 + 5

AB = 25 units

Use the distributive property 5(x-5)=5 I need help asap :(

Inessa [10]

5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.

Answer:

C. 3⁶

Step-by-step explanation:

Exponents with the same base follow this exponential rule for division:

xᵃ/xᵇ = xᵃ⁻ᵇ

When the bases are the same, we can subtract the exponents.

The bases are the same in this problem: 3. Therefore, we can subtract the exponents from each other:

3⁸/3²
3⁸⁻²
3⁶

The final and correct answer is C. 3⁶.
