Answer:
Yes, this is correct.
Step-by-step explanation:
Assuming the first equation was a = b, yes. a * c = a * b will also be true. This is known as the Multiplication Property of Equality
<span>The diagonals of a parallelogram bisect each other.
So we just equate the two equations BE and DE
2x^2 - x = x^2 + 6
2x^2 - x - x^2 - 6 = 0
x^2 - x - 6 = 0
This is quadratic eqn. So we obtain.
(x - 3) ( x + 2) = 0
Setting each to 0 and solving for x, we have that x = 3 and x = -2
So we have two possible values for BD.
But Since BE = DE then we can simply double each
If x = 3 BD = 2 (2(3)^2 - 3) = 2 ( 18 - 3) = 30 units
If x = - 2 BD = 2((-2)^2 -3 ) = 2 (8 - 3) = 10 units</span>

Answer:
37 cm
Step-by-step explanation:
4300 is your principal
1.8% interest rate (change it into decimal form; 0.018)
2 years is our time
We'll now multiply our variables.
4300 x 0.018 x 2 = 154.80
This shows that in 2 years at their interest rate that they have earned 154.80.
We will add the $154.80 to the original borrowed amount of 4300.
$4454.80 will be how much they will owe after 2 years.
To find out the amount in 15 months we'll divide 15 months by 12 and we get 1.25 and now we multiply the numbers again.
4300 x 0.018 x 1.25 = 96.75
They will pay $96.75 in interest within 15 months and we'll add it to the 4300.
$4397 will be how much they will pay after 15 months.
