Answer:
<h2>x = 30°</h2>
Step-by-step explanation:
The angle 30° and 2x are complementary angles.
Two angles are called complementary angles, if their sum is one right angle (90°).
Therefore we have the equation:
30 + 2x = 90 <em>subtract 30 from both sides</em>
2x = 60 <em>divide both sides by 2</em>
x = 30
Answer: Use the formula y = mx + b in order to solve for b. Then, plug in known vaules.
y= -13x -57
Step-by-step explanation:
y = mx + b
5 = 12(-3) + b
5 = -36 + b
b = 41
y = -3x + 41
Answer:

Step-by-step explanation:
8-3=5
1) Let's write out both expressions subtracting 4m²+2mn+8n² from 2m²+6mn+2n²
2) Note that when we subtract 4m^2 + 2mn + 8n^2 from 2m^2 + 6mn + 2n^2 we need to swap the sign by placing -1 outside the parentheses and then combine like terms adding those terms algebraically.
