Answer:

Step-by-step explanation:

We need to simplify this equation:

6.9 - 5 + 4.1

The reason why there is a negative sign in between 6.9 and 5 is that + and - become negative.

There is a chart that can help you with this:

+ + = +

+ - = -

- + = -

- - = +

This will help you with BIDMAS/BEDMAS

What is the value of the expression 5x2 + 2x when x = 5?

masha68 [24]

Answer:

135

Step-by-step explanation:

Given:

$x = 5$

To determine a numerical value for the expression, simply substitute the value of "x" into the expression and simplify the expression, if necessary, to determine a specific number for the expression provided.

$\implies 5x^{2} + 2x$

$\implies 5(5)^{2} + 2(5) \longrightarrow \longrightarrow \longrightarrow (x = 5)$

$\implies 5(5)(5) + 2(5)$

$\implies 125 + 10$

$\implies 135$

Therefore, the value of the expression $5x^{2} + 2x$ when x = 5 is 135.
