Given that f(x)=2x+3 , find: f(5x+3)

Mathematics
1 answer:
PIT_PIT [208]2 years ago
5 0

Answer:

f(5x+3) = 10x + 9

Step-by-step explanation:

f(x) = 2x + 3

f(5x+3) = ??

Given this information, we know that x = 5x + 3. Therefore, to solve the new equation we need to plug 5x + 3 into the original equation

f(5x+3) = 2(5x+3) + 3

Now we distribute the 2

f(5x+3) = 10x + 6 + 3

Finally, combine like terms

f(5x+3) = 10x + 9

P(x)=x^3+2x^2-4x-8 how do you factor this polynomial function
Wewaii [24]
<h2>Steps:</h2>

So for this, I will be factoring by grouping. Firstly, factor x³ + 2x² and -4x - 8 separately. Make sure that they have the same quantity inside of the parentheses:

p(x)=x^2(x+2)-4(x+2)

Now we can rewrite it as:

p(x)=(x^2-4)(x+2)

However, we aren't finished factoring yet. The first factor, x² - 4, can be factored further using the difference of squares. The difference of squares goes by the formula here: x^2-y^2=(x+y)(x-y) . In this case:

x^2-4=(x+2)(x-2)\\p(x)=(x+2)(x-2)(x+2)

<h2>Answer:</h2>

<u>In short, the answer is p(x)=(x+2)(x-2)(x+2)\ \textsf{OR}\ p(x)=(x-2)(x+2)^2</u>

attashe74 [19]

Answer:

4 yards

Step-by-step explanation:

the formula for finding the volume of a shape is volume= to length times with times how tall it is. In this case we do not have the hight so we make a formula. 5 and 3/4 times 10 times hight = to 230. If you do the math you get 4 yards as the answer.
