The product of 3a + 5 and 2a2 + 4a – 2 is , the correctoption is A.
When two algebraic expressions are multiplied, the result is called the product, and the two expressions making up the product are called factors and multiplicands.
The multiplication of two algebraic equations can be expressed as a × b.
The product of 3a + 5 and 2a2 + 4a – 2 is determined in the following steps given below.
Hence, the product of 3a + 5 and 2a2 + 4a – 2 is .

Answer:
6a3 + 22a2 + 14a - 10
Step-by-step explanation:
(3a + 5) x (2a^2 + 4a - 2)
= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)
= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10
= 6a^3 + 22a^2 + 14a - 10
Factor completely: a2 - a - 20
Answer:
b² + 12b + 32 = (b + 8)(b + 4)
a² - a - 20 = (a - 5)(a + 4)
Step-by-step explanation:
To factor, let's find two numbers that multiply to 32, and add to 12.
I find the two numbers as 4 and 8.
We can expand 12b as 4b + 8b, and factor the pairs.
The factored form is (b + 8)(b + 4)
Using the same process, find two numbers that multiply to -20 and add to -1
The numbers are 4 and -5
The factored form is (a - 5)(a + 4)
Answer:
$900 was the profit made for the month
Step-by-step explanation:
in this question, we are simply asked to calculate the amount of money a website made the owner if there is a certain number of subscriptions that month and a certain number of cancellations by old subscribers too.
From the question, we can see that 100 subscribers paid for subscription with 10 members canceling.
$10 is the subscription fee, the total amount made by the subscriptions is thus 10 * 100 = $1,000
in opposite light, there were 10 cancellations, the amount lost due to these would be 10 * 10 = $100
The profit made by the website would thus be ;
$1000 - $100 = $900
Answer:
Z=+6
Step-by-step explanation:
Z^5=-7776i
Let's note that i I mathematics means negative one i.e
i = -1
So the equation is equal to
Z^5=-*-(7776)
Z^5 = 7776
Z= 5√7776
Since it's a divisible by 6
It's giving us a clue that 6 it's the answer.
Ok let's check the 5th root of 7776 in our calculator.
Z=+6
+6 is the solution to the equation
Z^5=-7776i
