If we let x as the amount of money saved per month and m be the number of months:
xm = 300m2 + 120m 180
The quadractic equation would result to:
300m2 + (120-x)m + 180 = 0
Using the quadratic formula we have the following factorization:
(m - ( -120 + x + sqrt (x2 - 240x - 2145600) ) / 600) (m - ( -120 +x - sqrt (x2 - 240x - 2145600) ) / 600) = 0
Answer:
yes
Step-by-step explanation:
2+2+2=6
3+3=6
If you multiply a negative number by a positive number, you get a negative product. if you were to multiply two positive or two negative numbers, you'd get positive products.
Answer:
324ft^2
Step-by-step explanation:
rectangle: 22ft X 12ft = 264ft^2
trapazoid: 1/2(22+8)4 = 60ft^2
264 + 60 = 324ft^2
hope this helped!! :D
tell me if you need further explaination!
Answer:
$3781.19
Step-by-step explanation:
Let us assume that the student has to earn $(1900 + x) by September 1 so that he can pay the $1900 tuition fee by September 1 and the remaining $x will grow at 3% simple interest to make him able to pay another tuition fee of $1900 by January 1.
So, we can write 
{Because September 1 to January 1 is 4 months and the monthly simple interest rate is 
%}
⇒ 1.01x = 1900
⇒ x = $1881.19 (Rounded to the nearest cents)
Therefore, the student has to earn $(1900 + 1881.19) = $3781.19 (Answer)
