The answer is -11/2, 9/2

Explanation

You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10

Then you solve for X in each equation.
2x+1=10 would give you 9/2

2x+1=-10 would give you -11/2

So your final solutions would be x1= -11/2 x2= 9/2

Why are some rational numbers not integers?
Mariana [72]

Answer:

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

4- What are the different waysto solve a quadratic? List examples of each
TiliK225 [7]
I know of two ways to solve quadratic equations. The first is through factoring. Let us take the example (x^2)+2x+1=0. We can factor this equation out and the factors would be (x+1)(x+1)=0. To solve for the roots, we equate each factor to 0, that is

x+1=0; x+1=0

In this case, the factors are the same so the root of the equation is

x=1.

The other way is to use the quadratic formula. The quadratic formula is given as [-b(+-)sqrt(b^2-4ac)]/2a where, using our sample equation above, a=1, b=2 and c=1. Substitute these to the formula, and you will get the same answer as the method above.

Answer:

V=12.167

Step-by-step explanation:

V=s^3

V=2.3x2.3x2.3

V=12.167

Since it is cubic centimeters, then it is written as 12.167cm^2
