Mathematics
1 answer:
shusha [124]3 years ago
3 0

Answer:

I think the right answer would be 7

Step-by-step explanation:

We got-ta use the equation: CA * BA = DA²

CA = 15 + BA

DA² = 8² = 64

=> (15 + BA) BA = 64

Subtract 15 from each side:

BA(BA) = 49

BA² = 49

Now take the square root of each side

BA = 7

Hope this helps!

Frank purchased an air conditioner for $3000. Its value depreciates at a rate of 8% each year. How much will the air conditioner
Lina20 [59]

Answer:

$2280

Step-by-step explanation:

Given: Cost of Air conditioner= $3000.

            Rate of depreciation= 8%

            Number of year= 3 years.

Now, finding the depreciation for 3 years.

Depreciation= \frac{Cost\ of\ air\ conditioner\times rate\ of\ depreciation\times years}{100}

Amount of depreciation= \frac{\$ 3000\times 8\times 3}{100} = \$ 30\times 24

∴ Amount of depreciation in 3 years is $720.

Cost of Air conditioner after 3 years= Original\ cost - Amount\ of\ depreciation

⇒ Cost of Air conditioner after 3 years= \$ 3000-\$ 720= \$ 2280.

∴ Cost of Air conditioner in 3 years is $2280.

How is factoring a trinomial different than factoring a number?
JulijaS [17]

Answer:

Hope this answers the question.

Step-by-step explanation:

Factoring a number: If you use the number 10, for example, you have to find all the factors to factor it. 1, 2, 5, 10.

Factoring a trinomial: If you use the trinomial x^2 + 16 + 64, for example, to factor it you need to first find what numbers multiply up to 64 and also add up to 16. In this case, those numbers are 8, and so you get (x + 8)^2.
