gfgfgfgfgfg
Step-by-step explanation:
Is it subtract 228? if so then 3-5 equals -2. -2-8 equals -10. -10-228 equals -238
Actual length = 3.5 × 120
actual length = 420 cm
actual length = 4.2 m
actual width = 2.5 × 120
actual width = 300 cm
actual width = 3 m
actual area = l × w
actual area = 4.2 × 3
actual area = 12.6 m²
the answer is b
Community property of addition because -6 + 6 would equal zero
Answer:
y = 8 or y = -14
Step-by-step explanation:
Solve for y over the real numbers:
abs(y + 3) - 4 = 7
Add 4 to both sides:
abs(y + 3) = 11
Split the equation into two possible cases:
y + 3 = 11 or y + 3 = -11
Subtract 3 from both sides:
y = 8 or y + 3 = -11
Subtract 3 from both sides:
Answer: y = 8 or y = -14
