Which product is equivalent to 25x2 – 16?(5x − 4)(5x + 4)
(5x + 8)(5x − 8)
(5x − 4)(5x − 4)
(5x − 8)(5x − 8)

Answers

Answer 1
Answer:

The product that is equivalent to the given expression is: A. (5x-4)(5x+4)..

What are Equivalent Expressions?

Equivalent expressions are expressions that have equal value when simplified.

(5x-4)(5x+4) is equivalent to  25x² – 16 because if we expand we would have:

5x(5x+4) -4(5x+4)

5x² + 20x - 20x - 16

Add like terms

25x² – 16

Therefore, the product that is equivalent to 25x² – 16 is: A. (5x-4)(5x+4).

If an object has a mass of 50 kilograms, what would it weigh on Uranus, where the acceleration due to gravity is. 10.5 meters/second2?

Answers

Mass of n object : m = 50 kg.
On Uranus : g ( Uranus ) = 10.5 m/s²
Weight = Mass   x  Acceleration due to gravity
Weight = 50 kg · 10.5 m/s² = 525 kgm/s² = 525 N

A student factors 3x2 – 12 to the following. 3(x2 – 4) Which statement about 3(x2 – 4) is true? A. The expression is equivalent, and it is completely factored. / B.The expression is equivalent, but it is not completely factored./ C. The expression is not equivalent, but it is completely factored./ D.The expression is not equivalent, and it is not completely factored.

Answers

Answer:

Option B is correct that is the expression is equivalent, but it is not completely  factored.

Step-by-step explanation:

We have given an expression

3x^2-12

when we take the common factor out which is 3 from the expression we will get

3(x^2-4)

This expression is equivalent but is not completely factored because the term

(x^2-4)\text{can be further factored as}(x-2)\text{and}(x+2)\text{from the formula}a^2-b^2=(a+b)(a-b)

Hence, Option B is correct.

Option C and D are discarded because given factor is equivalent  

Option A is discarded  because expression is not completely factored.

 

B. The expression is equivalent but not completely factored.

You can continue to factor

3 (x^2-4) =

3 (x+2)(x-2)

a boat cost 12,050 and decreases in value by 12% per year. How much will the boat be worth after 9 years

Answers

Given:
Cost = 12,050
depreciation rate = 12%

year   beginning value      dep.rate    depreciation  ending value
1        12,050.00               12%         1,446.00    10,604.00
2        10,604.00               12%         1,272.48      9,331.52
3          9,331.52               12%         1,119.78      8,211.74
4          8,211.74               12%            985.41      7,226.33
5          7,226.33               12%            867.16      6,359.17
6          6,359.17               12%            763.10      5,596.07

8          4,924.54               12%            590.94      4,333.60
9          4,333.60               12%            520.03      3,813.56

The boat will be worth $3,813.56 after 9 years.

Depreciation = beginning cost x depreciation rate
Ending cost = beginning cost - depreciation

Depreciation is the wear and tear of an object that decreases its value.
