Combining those like terms would end as 3n.

Explanation: The end of a subtraction equation is basically just the negative number, except you add it to the other part.

For example, 2n is really -2n, and you just add -2n to 5n (which is positive,) and you get 3n.

Answer:

$ 50,340.97

Step-by-step explanation:

From the above question, we can deduce that we are to find the Initial amount invested which is also called the Principal.

The formula to find Principal in a compound interest question is:

P = A / (1 + r/n)^nt

Where:

A = Total Amount obtained after invested = $80,000

r = Interest rate = 3.1% = 0.031

n = number of times interest in compounded = Quarterly = 4

t = time in years = 15

P = $80,000/(1 + 0.031/4)^4 × 15

P = $80,000/(1 +0.00775)^60

P = $ 50,340.97

Hence, James would have to invest $50,340.97 today to have $80,000 in 15 years.

Answer:

The largest side of given triangle is: AB

Step-by-step explanation:

In order to find the largest side, we have to find all the triangles first.

The two angles at point A will sum up to 180° as the angles on the straight line are supplementary.

So,

$136 + Angle\ A = 180\\Angle\ A = 180-136 = 44$

∠A = 44°

∠C = 71°

The sum of interior angles of a triangle is 180°

Using this:

∠A+∠B+∠C = 180°

44°+∠B+71° = 180°

∠B+115° = 180°

∠B = 180°-115°

∠B = 65°

In a triangle, the side opposite to the largest angle is the largest. In the given triangle, ∠C is the largest so the side AB which is opposite to ∠C is the largest.

Hence,

The largest side of given triangle is: AB
