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}}

Is it possible to draw a triangle with numbers 5,6,11
Tatiana [17]

Answer:

No

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is a^2 + b^2 = c^2\\.  

11 is the bigger side in this case, so our formula would go like this: 5^2 + 6^2 = 11^2\\.

We now calculate to see if this is true.

25 + 36 \neq 121

Therefore, the answer is wrong.
