Given 6(x) = (x+41, what is b(-10)?

prisoha [69]

The value of $b(-10)$ is 31

Explanation:

The given expression is $b(x)=x+41$

We need to determine the value of $b(-10)$

The value of $b(-10)$ can be determined by substituting $x=-10$ in the expression $b(x)=x+41$

Thus, we have,

$b(-10)=-10+41$

Adding the terms, we have,

$b(-10)=31$

Thus, the value is 31.

Therefore, the simplified value of the expression by substituting $x=-10$ in the expression $b(x)=x+41$ is 31.

Cual es el volumen del cubo de rubick cuya arista mide 3 cm

Natasha2012 [34]

For this case we are asked the following question:

"What is the volume of the rubick's cube whose edge measures 3 cm"

By definition, the volume of a cube is given by:

$V = l ^ 3$

Where:

l: Is the side or the edge of the cube

According to the statement we have:

$l = 3 \ cm$

Substituting:

$V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27$

Finally, the volume of the cube is $27 \ cm ^ 3$

Answer:

$27 \ cm ^ 3$
