not really sure
Step-by-step explanation:
bc i don’t kno
we are given
numbers are 1.4 units from −3.2 on a number line
so, we will add and subtract 1.4 to -3.2
Addition:
-3.2+1.4=-1.8
Subtraction:
-3.2-1.4=-4.6
so,
option-a and option-c..........Answer

Step-by-step explanation:
3(-5+2x)=21
-15+6x=21 -5*3 is -15
6x=36
x=6
Answer:
P43=4!(4–3)!=241=24 24 possible choices
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
