Answer:
Step-by-step explanation:
10+20+40=70
70*0.8=7*10*0.8=56 L (We Deliver)
total area =2*(10+20)*40+2*10*20=2*30*40+400=2400+400=2800 cm^2
2800*0.02=28*100*0.02=28*2=56 L (Go Parcels)
1. 90 2. 8000 3. 500 4. 200,000
Multiply 5x to 3x and -2
multiply 6 to 3x and -2
15x^2-10x+18x-12
15x^2+8x-12
₇P₅ is a permutation. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nPr = 
₇P₅ = 
= 
= 
= 7 * 6 * 5 * 4 * 3
= 2520
