Answer:
5x + 5 = 45
you subtract 5 on both sides of the equation
5x + 5 = 45
- 5 - 5
which leaves u with 5x = 40
Step-by-step explanation:
Answer:
Pythagorean Theorem: a^2 + b^2 = c^2
6^2 + 15^2 = c^2
36 + 225 = 261
So, the answer is 261

Answer:
C=2.22 i^ + 1.85 j^
Step-by-step explanation:
If vector C is perpendicular to vector A, that means the scalar product between C and A is 0, so if C= X i^ + Y j^, using the scalar product definition we can write an equation:
Now since we know the scalar product between C and B is 20, we can write another equation:
From the first equation we have that:
And now we can replace the X in the 2nd equation:
Solving, we have that Y=1.85, and using this value we can find X=2.22. You can confirm that C is correctly since:
