As we know that the area of a rectangle is -
length × Breadth
So, here length = (3n+1)
Breadth = (2n-5)
Area of rectangle
= (3n+1)(2n-5)
= 3n(2n-5)+1(2n-5)
= 6n² - 15n + 2n - 5
= 6n² - 13n - 5
Answer) Area of rectangle is 6n² - 13n - 5
Answer:
- 7% interest = $10,000
- 13% interest = $20,000
Step-by-step explanation:
First find out what an 11% return on $30,000 is.
= 11% * 30,000
= $3,300
Use simultaneous equations.
Assume the amount to be invested in to make a 7% interest is x and the amount for a 13% interest is y.
0.07x + 0.13y = 3,300
x + y = 30,000
y = 30,000 - x
0.07x + 0.13 (30,000 - x) = 3,300
0.07x + 3,900 - 0.13x = 3,300
0.07x - 0.13x = 3,300 - 3,900
-0.06x = -600
x = -600 / -0.06
x = $10,000
y = 30,000 - x
= 30,000 - 10,000
y = $20,000
Answer:
Step-by-step explanation:
24$ I believe is the answer You divide the total number of miles driven, to the number of miles per gallon . 180 divided by 30 = 6. Then multiply the answer 6 times dollars per gallon 4$ • 6 = 24 Your answer is 24 :)
one root ie -8 cause there is limit for x ie x lies between -infinity to 0 so 8 cant be root
therefore -8 is only one root for ur question
