Answer:

Step-by-step explanation:

3(x + 3) = 12

Multiply 3 by both numbers in the parentheses.

3x + 9 = 12

Subtract 9 from both sides of the equation.

3x = 3

Divide 3 from both sides of the equation.

x = 1

-98=4x-2(5x+13)

shutvik [7]

Well use the distributive property

-98=4x-2(5x+13)

Now multiply 2 times 5x+13

-98=4x-10x-26

Now combine like terms

-98=-6x-26

Now get 26 on the other side by adding it to -98

-6x=-72

x=12

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

Hello!

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

❖ The unknown number is 6.

15 - 9 = 6

To find the value of the second expression you can subtract 9 from both sides:

9 - 9 = 0

15 - 9 = 6

Therefore, ? = 6.

shusha [124]

Answer:

$f'(x) = {e}^{x}( \sin x + \cos x )$

Step-by-step explanation:

$f(x) = {e}^{x} \sin x \\ \\ f'(x) = \sin x \frac{d}{dx} {e}^{x} + {e}^{x} \frac{d}{dx} \sin x \\ \\ f'(x) = \sin x \: {e}^{x} +{e}^{x} \cos x \\ \\ f'(x) = {e}^{x}( \sin x + \cos x )$
