Answer:
SA = 126 square cm
Step-by-step explanation:
SA = 2(l · w) + 2(h · w) + 2(l · h)
SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)
SA = 60 + 36 + 30
SA = 126 sq cm
Answer:
b, y = 9x + 7
Step-by-step explanation:
Since the graph y = 9x + 10 is being "translated" 3 units down, that means the slope of the equation remains the same, but the y intercept is being moved 3 units down.
y = mx + b
y-intercept = b = 10
10 - 3 = 7
the answer is b, y = 9x + 7
