I'm lost I messed up how do I delete my answer...
Answer:
3. 18 + 18 + 7 + 7 = 50
4. 120 degrees
Step-by-step explanation:
She was not supposed to "undistribute" and separate 3x+1 she was supposed to subtract 1 from both sides
Knowing that a square gives the optimum area;
120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s
Therefore, the length should be ≈10.95"
Hope I helped :)
