Answer:
x>1/2
Step-by-step explanation:
2x+1−8x<8x−2−8x
−6x+1<−2
−6x+1−1<−2−1
−6x
/−6
<
−3
/−6
x>1/2
So $280 • 30x
X would be 4
So 30 • 4 + 120
Week 1 - $310
Week 2 - $340
Week 3 - $370
Week 4 - $400
Total after for weeks of saving : $400

Answer:
-5+12i
Step-by-step explanation:
(2+3i)^2
2^2+2×2×3i+(3i)^2
4+2×2×3i+(3i)^2
4+2×2×3i+3^2i^2
4+2×2×3i+9i^2
4+2×2×3i+9×-1
4+12i+9×-1
4+12i-9
(4-9)+12i
-5+12i
