Hello,
If an equation is an identity, then every value of the variable makes the egality true.
Generaly we resolve an equation in R.
In this case Sol=R
To simplify this improper fraction we can turn it into a mixed number. The fact that the denominator is 2 and the numerator isn't divisible by 2 shows that it can't simplified any further as a improper fraction.
23/2 = 11 1/2
Best of Luck!
Answer:
The answer is true because line f is seen on the plane R
Answer: 4 m
Step-by-step explanation:
Let the amount each dimension was increased by be x.
Now we can set up a equation.
(2+x)(4+x) = 48
8 + 2x + 4x + x^2 = 48
x^2 + 6x - 40 = 0.
We can factor the left side of the equation.
(x+10)(x-4) = 0.
Therefore, x equals either -10 or 4. Since you can't increase a dimension by a negative amount, x must equal to 4.
The answer is x=-16
2/3x-1/6x=-8 (combine like terms)
3/6x=-8
1/2x=-8
x=-16
Hope this helps
