Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
is the result of multiplying (3x-1) to the second power and (x+6) to the second power
<h3><u>Solution:</u></h3>
Given that we have to find the result of multiplying polynomials (3x-1) to the second power and (x+6) to the second power
"Second power" means the term is raised to power of 2
Therefore,
We have to multiply 
We can use the algebraic identity to expand the above expression
Applying these in above expression, we get
Multiply each term in first bracket with each term in second bracket
Simplify the above expression
Combine the like terms
Thus the above expression is the result of multiplying (3x-1) to the second power and (x+6) to the second power
Answer:
60
Step-by-step explanation:
step one: ADD.
Perhaps you meant <span>(a^3+14a^2+33a-20) / (a+4), for division by (a+4).
Do you know synthetic division? If so, that'd be a great way to accomplish this division. Assume that (a+4) is a factor of </span>a^3+14a^2+33a-20; then assume that -4 is the corresponding root of a^3+14a^2+33a-20.
Perform synth. div. If there is no remainder, then you'll know that (a+4) is a factor and will also have the quoitient.
-4 / 1 14 33 -20
___ -4_-40 28___________
1 10 -7 8
Here the remainder is not zero; it's 8. However, we now know that the quotient is 1a^2 + 10a - 7 with a remainder of 8.
