132msq.
square=6×6×3
triangle= 1/2×4×6×2
add both
answer we will get 132 metre sq.
Based on the scenario, the initial temperature would be :
28 = (60) (1/2)^x/30 + 20
(60) (1/2)^0/30 + 20 = 60 + 20 =
80 C
Hope this helps
Answer:
9
Step-by-step explanation:
Given
p(x) = 5x² - 3x + 7 ← substitute x = 1
p(1) = 5(1)² - 3(1) + 7 = 5(1) - 3(1) + 7 = 5 - 3 + 7 = 9
