Answer:40z
Step-by-step explanation: i got this answer by using the distributive property. So when I distribute 5 to 8 you just basically multiply the two and add the variable on the end
You plug in 7 for every x that there is.
24(7)-7=161
5((7)^2)-5+15=255
2(7+2)+2(7)=32
NPr = n! / (n-r)!
8P4 = 8! / (8-4)!
= 8! / 4!
= 1,680
Distance= √((x2-x1)²+(y2-y1)²) = √((6-3)²+(0-2)²)=√(9+4)=√13 ≈ 3.61
