Let's simplify step-by-step.

3x2(x2−4x−4)+5x3+7x2+2x+11

Distribute:

=(3x2)(x2)+(3x2)(−4x)+(3x2)(−4)+5x3+7x2+2x+11

=3x4+−12x3+−12x2+5x3+7x2+2x+11

Combine Like Terms:

=3x4+−12x3+−12x2+5x3+7x2+2x+11

=(3x4)+(−12x3+5x3)+(−12x2+7x2)+(2x)+(11)

=3x4+−7x3+−5x2+2x+11

Answer:

=3x4−7x3−5x2+2x+11

4n-3=-2n+9 What is the value of the variable 'n'?

julsineya [31]

4n - 3= -2n + 9
add 3n to both sides

4n= -2n +12
add 2n to both sides

6n= 12
divide both sides by 6

n= 2

Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5

Hope this helps! :)

A refrigeration system at your company uses temperature sensors fixed to read Celsius (°C) values, but the system operators in y

Anton [14]

Answer:

14°F

Step-by-step explanation:

We are given that,

The label for the high temperature is -10°C.

It is required to label the alarm in Fahrenheit (°F).

As we know,

(1°C × $\frac{9}{5}$ ) + 32 = 33.8°F

Thus, for -10°C, we have,

(-10°C × $\frac{9}{5}$ ) + 32 = -18 + 32 = 14°F

Hence, the Fahrenheit value on the label will be 14°F.
