I think this is the answer... plz don't get mad if this is wrong
Idk it’s seems idk idk idk
Let us use 360 days for the 1 year term.
principal = 1,200interest rate = 8% unless otherwise stated, this rate is per annum or annual rate.term = 240 days
Simple Interest = Principal * interest rate * termS.I = 1,200 * 8% * 240/360S.I = 1,200 * 0.08 * 0.667S.I = 64.032 rounded off to 64
Answer:
4.39 to 2DP.
Step-by-step explanation:
x * (x - 2) = 28
x^2 - 2x = 28
Solving by completing the square:
(x - 1)^2 - 1 = 28
(x - 1)^2 = 29
x = +/-√29 + 1
x = 6.38516, -4.38516
x must be positive so it = 6.38516.
The shortest side = x - 2 = 4.385.
Answer: x = 115/2 and 119/6
You can simplify the answer.
Step-by-step explanation:
(2x + 5)(6x -1)= 120
120 = (2x +5) and (6x -1) = 120
120 - 5 = 2x and 6x = 120 - 1
115 = 2x and 6x = 119
115/2 = x and x = 119/6
