Answer:
(A) 6x³+8x² + 4x - 4, but only if my change is correct to <u>6x³5x² - 2</u> is correct.
Step-by-step explanation:
<u>Is "g(x) = 6x³5x² - 2" meant to be g(x) = 6x³-5x² - 2?</u>
<u>If so,</u> (f+g)(x) = 3x² + 4x - 6 - (6x³-5x² - 2)
(f+g)(x) = 3x² + 4x - 6 - 6x³+5x² + 2
(f+g)(x) = 6x³+8x² + 4x - 4
(A)
Using simple interest, it is found that she would have to pay the loan back on May 17.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
In this problem, the parameters are:
Solving for t, we have that:
Considering a year has 365 days:
0.125 x 365 = 46
46 days after April 1, hence she would have to pay it back on May 17.

Given that those lines are parallel they will form similar traingles. This means the lengths of the sides of the triangles will be proportional through a ratio.
Find the ratio: divde the given small side by the given big side(they must be the same sides of the triangles though)
For example:
I found the ratio by dividing 8 / (20) and simplify to
2/5
Next step: multiply 22 by the fraction to get "y"
22*
= y
y=8.8 units
To find x :
Step 1: write an equation for the length of side US.
US= 5+x-2=
x+3
Step 2: DIVIDE 5 by the ratio (must divide to get longer side DO NOT multiply)
US= 5/(2/5)= 12.5 units
Step 3: set the expression you found for US equal to 12.5
12.5= x+3
subtract 3 from both sides to isolate x.
x= 9.5 units
My answers:
x= 9.5 units
y= 8.8 units
Answer:
Your answer for this problem would be A.
Step-by-step explanation:
This is the only answer that makes sense and you could not add 3x or 5x because it would be adding numbers instead of getting rid of them.
