Simplify the radical by breaking the radicand up into a product of known factors.
Answer:
Aseem’s : 8.3, Stana’s : 11.6
Step-by-step explanation:
Aseem: x
Stana: 2x-5
X+2x-5=20
3x=25
X = 8.3
The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 11.66.
Let's define the length of Aseem's car as x. Stana's car is 5 less than 2 times the length of Aseem's car, so the length of Stana's car can be represented as 2x - 5. The sum of the lengths of both cars is 20, so we can set up the equation x + (2x - 5) = 20. Solving this equation will give us the lengths of Aseem's and Stana's cars.
Combining like terms, we get 3x - 5 = 20. Adding 5 to both sides of the equation, we have 3x = 25. Finally, by dividing both sides by 3, we find that x = 8.33.
The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 2(8.33) - 5 = 11.66.

Answer:
Let's say we have an expression x * y + z * w, where x, y, z and w are numbers.
We can use the commutative property to change the order of the summands:
x * y + z * w = y * x + w * z = (y + z) * x + w
Since we have a sum of two products, we can use the associative property to combine them:
(y + w) * (x + 15) = 160
By dividing both sides of the equation by 2, we get:
(y + w) / 2 * (x + 15) / 2 = 80
We can then simplify this expression using the distributive property:
(y / 2) + (w / 2) * (x / 2) + (15 / 2)
Since the numbers are all positive, we can cancel out the halves on the left, and combine the remaining terms:
y / 2 + (w / 2) * x + 15 / 2 = 80
Finally, we can simplify this expression by dividing both sides of the equation by the constant fraction:
y / 2 + (w / 2) * x + 15 / 2 = 80
(y / 2) + (w / 2) * (x / 2) + (15 / 2) = 80
Simplifying this expression, we get y / 2 + (w / 2) * x / 2 + 15 / 2 = 40.
By simplifying the last term further, we get:
y / 2 + (w / 2) * x / 2 + 7.5 = 40
Therefore, the equation that simplifies to 160 is this one:
y / 2 + (w / 2) * x / 2 + 7.5
I hope this helps!
