Answer:B- rectangle
Step-by-step explanation:
equation- 9 × 5 = 45
mr. stevens worked for 45 hours last week
(2.2x10^-1)=22x10^-2
(22x10^-2)+(2.3x10^-2) = 24.3x10^-2
=2.43x10^-1
Therefore, the answer is D
So lets add the common fractions 3/4+3/4+1/4+1/2=7/4+1/2=18/8, now the whole numbers 3+1+2+4+2=12, so 12 18/8 and simplify 14 2/8= 14 1/4 <span />
