Answer:
Step-by-step explanation:
-8 + 6(b - 1) = -8 +6b-6 = 6b -14
Answer:
Step-by-step explanation:
2) l = 9 cm
b = 7 cm
h = 3 cm
Surface Area= 2*(lb + bh + hl)
=2*(9*7 + 7*3 + 3*9)
=2*(63 + 21 + 27)
= 2 * 111
= 222 cm²
(4*a)*2
lets give a a number: a = 3 so (4*3)*2 = 12*2 = 24
lets try the options:
A) 4 *(3*2) = 4*6 = 24 = the same
B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different
C) 8*3 = 24 = same
D) 4*2+3*2 = 8 +6 = 14 = different
E) 2*(4*3) = 2*12 = 24 = same
so A, C & E would be the equivalent.
Answer:
28%
Step-by-step explanation:
Hello,
When the item is reduced by 10%, this is like we multiply this price by 1-0.10=0.90
When the item is reduced by 20%, this is like we multiply this price by 1-0.20=0.80
When the item is reduced by 10% and then by 20%, this is like we multiply this price by 0.90*0.80=0.72
so this is equivalent that the item is reduced by 28% (as 1-0.28=0.72)
hope this helps
