Answer:
x=+/-3
Step-by-step explanation:
x^4-5x^2-36=0
factor
(x^2-9)(x^2+4)=0
split into 2 equations because one of these terms will need to equal zero for the eqation to be true
x^2-9=0 x^2+4=0
x^2=9 x^2=-4
x=+/-3 no real numbers
1. Add all the sides 33 inches left and right and 75 inches. up and down.
Perimeter= 216
2. If 2/3 pounds is needed for 1 cheese cake and you have 2 pounds its not enough so 2 minus 2/3 will give you a mixed fraction : 1 over 1/3 or a decimal : 1.3
Idk if they want you to divide but if they do then your answer is 1/3
Answer:
2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
