Step-by-step explanation:
<u>Step 1: Define Equation</u>
2b + 5 = 2
<u>Step 2: Solve for </u><em><u>b</u></em>
- Subtract 5 on both sides: 2b = -3
- Divide 2 on both sides: b = -3/2
Answer: sqrt(58)
Step-by-step explanation:
Answer:
424--------------------------------------------------------
1. 7 + 15 + 12 + 5 + 5 + 10 = 54
54 x 2.5 = $135
The correct answer is $135
2. A^2 + 9^2 = 22^2
A^2 + 81 = 484
A^2 = 403
Square root of a and 403
A= 20.7
20.7 + 22 + 9 = 51.7
The correct answer is (3)
Check the picture below.
recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.
