Evaluate the given expression at x= -4 -3x + 2x^2 + 2

Mkey [24]

Answer:

$\huge{ \boxed{ \bold{ \text{46}}}}$

Step-by-step explanation:

If the value of variables of algebraic expression are given, the value of the term or expression can easily obtained by replacing the variables with numbers.

$\text{ \underline{ Given}} : \text{x = - 4}$

$\text{ \underline{ To \: find}} : \sf{value \: of \: - 3x + 2 {x}^{2} + 2}$

$\text{ Plug \: the \: value \: of \: x}$

$➝ \: \sf{ - 3 * (- 4 )+ 2 * {( - 4)}^{2} + 2}$

$\text{Remember!} : \text{Multiplying \: a \: negative \: integer \: by \: negative \: integer \: gives \: a \: positive \: integer.}$

➝ $\sf{12 + 2 * {( - 4)}^{2} + 2}$

$\text{Evaluate \: the \: power}$

➝ $\text{12 + 2 * 16 + 2}$

$\text{Multiply \: the \: numbers}$

➝ $\text{12 + 32 + 2}$

$\text{Add \: the \: numbers}$

$➝ \boxed { \text{46}}$

In a drawer there are 6 black socks,8 white socks,2 red socks, and 4 blue socks. A boy takes one socks from the drawer, without

galina1969 [7]

Answer:

1/5

Step-by-step explanation:

Chance is also referred to as probability

probability = Number of event/Total samples space

If there are 6 black socks,8 white socks,2 red socks, and 4 blue socks in a drawer, the total number of socks will be the sample space

Sample space = 6 + 8 + 2 + 4

Sample space = 20socks

Total number of blue socks is the event

Number of event = 4 blue socks

Chance that the socks is blue = n(E)/n(S)

Chance that the socks is blue = 4/20

Chance that the socks is blue = 1/5

What is the determinant of 15 18 154

IgorC [24]

Answer:

The determinant is 15.

Step-by-step explanation:

You need to calculate the determinant of the given matrix.

1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):

$\left[\begin{array}{ccc}-25&-23&9\\0&3&1\\-5&5&3\end{array}\right]$

2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):

$\left[\begin{array}{ccc}-25&-23&9\\0&0&1\\-5&-4&3\end{array}\right]$

3. Expand along the row 2: (See attached picture).

We get that the answer is 15. The determinant is 15.
