Answer:
a ≈ 1.8
Step-by-step explanation:
a / sin (180 - 105 - 15)° = 2 /sin 105°
a = (2 /sin 105°) x sin 60°
a = (2 / 0.97) x 0.87
a = 1.79 (≈ 1.8)
Answer:it is rational
Step-by-step explanation:
repeating decimals are rational
-2x + 6x - 6 + 4
4x -2 Is The Simplified Expression
Answer : The duration of the loan is, 6 months
Step-by-step explanation :
First we have to determine the discounted money.
Discounted money = $850 - $800 = $50
Thus, interest = $50
Now we have to determine the time of loan.
Formula used :
where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
For 1 year : 
For 12 months : 
Thus, the duration of the loan is, 6 months
Use ac method
for ax²+bx+c=0 when a≠1
multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b
2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that
2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero
y+3=0
y=-3
2y+3=0
2y=-3
y=-3/2
y=-3 and -3/2
it's factored form is (x+3)(2x+3)
