Answer:
(x+4)(x+9)=0. Your answer would be x=-4 and x=-9. Explanation:: (x+4)(x+9) x times x=x2 x(9)+x(4)=13x 4 times 9=36 = x2+13x+36.(x+4)(x+9)=0. Your answer would be x=-4 and x=-9. Explanation:: (x+4)(x+9) x times x=x2 x(9)+x(4)=13x 4 times 9=36 = x2+13x+36.
Answer:
a, b, d and f
Step-by-step explanation:
To find which equation will have a a mass less than 50 mg after 2 hours, we just need to use the value of x = 2 and then verify if the values of y are less than 50:
a. y = 100*(0.5)^2 = 25 -> apply
b. y = 500*(0.3)^2 = 45 -> apply
c. y = 80*(2)^2 = 320 -> doesn't apply
d. y = 10*(1.2)^2 = 14.4 -> apply
e. y = 30*(1.5)^2 = 67.5 -> doesn't apply
f. y = 80*(0.2)^2 = 3.2 -> apply
g. y = 100*(2)^2 = 400 -> doesn't apply
Answer: $1004.4
Step-by-step explanation:
Simple math
Hey!
First, you would take 349 and subtract 25 from it.(349-25=324) This gets rid of the down payment.
Next, you would divide 324 by 54. (324÷54=6)
It would take him 6 weeks!
Hope this helped! And make sure to check my calculations!
