Use the Pythagorean Theorem Formula

a^2+b^2=c^2

a=12

b=9

12^2+9^2=c^2

144+81=c^2

225=c^2

Square root 225 and c^2

c=15

Answer: c=15

(5•-3) - (4•-3) + -3 - (3•-3)

Dmitry_Shevchenko [17]

Use PEMDAS.

Parenthesis first.

(-15)-(-12)+3-(-9)

Next multiply,

(-15)+12+3+9 (two negatives get you a positive)

Finally, add and subtract:
-15+24=9

You get 9 as your answer.

Hope this helps!

Can someone please help me its urgent!!!!!!!!!!<br> 3x + 11 = 3x - 11

user100 [1]

Answer:

$\Large\boxed{\mathsf{\Rightarrow NO\quad SOLUTIONS}}$

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

Isolate by the x on one side of the equation.

<h3><u>SOLUTIONS:</u></h3>

First, subtract 3x from both sides.

$\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}$

Solve.

$\displaystyle \mathsf{11=-11}$

Sides are NOT equal.

$\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}$

Therefore, there are no solutions.
