A^2 + b^2 = c^2
The diagonal is the hypotenuse (c).
36.6^2 + b^2 = 42^2
1339.56 + b^2 = 1764
Subtract 1339.56 from both sides.
b^2 = 425.44
Square root both sides.
b = 20.6 inches
Answer:
x= -1
Step-by-step explanation:
2(x-2) = -6
1. Use distributive property
2x - 4 = -6
2. Add -4 to -6
2x - 4 = -6
+4 +4
2x = -2
3. Divide 2 to both sides to isolate x
2x/2 = -2/2
x= -1
