Answer:3(7)+2=23. 21+2=23
Step-by-step explanation:
3.006 rounded to the nearest tenth is 3.0. This is due to the fact that
the 6 rounded up will mean that the current 0 becomes 1, but this will
not be carried to the tenth when rounding up.
A^2 + 3b + c - 2d
(3)^2 + 3(8) + (2) - 2(5)
9 + 24 + 2 - 10 = 25
Change in value = 87 - 42 = 45
percentage change = 45/42 x 100 = 107%
