8=10-2 or
997=1000-3
so we can use distributive property
remember, a(b+c)=ab+ac
for the first one
8(997)=(10-2)(997)=997(10-2)=997(10)+997(-2)=9970-1994=7976
2nd one
8(997)=8(1000-3)=8(1000)+8(-3)=8000-24=7976
20 because 12 divided by 3 is 4. then you multiply 5 by 4. and you get 20.
ok so take 4:20 pm and subtract 4 hrs from it so they left at 12: 20 pm
hope this helps :)
Answer:
Scalene Triangle
Step-by-step explanation:
Defn
When all the three sides of the triangle are of different measures, it is a scalene triangle.
Answer:
see bottom
Step-by-step explanation:
divide through by 4
x2 - 2x - 3 = 0
x2 - 3x + x - 3 = 0
(x2 - 3x) + (x - 3) = 0
x(x - 3) + 1(x - 3) = 0
(x + 1) (x - 3) = 0
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
