(a+3)(a-2)
(a² -2a +3a - 6) =0
(a² + a - 6 ) = 0
Use splitting the middle term
a² + 3a - 2a - 6 = 0
a(a+3) - 2(a+3) = 0
(a-2)(a+3) = 0
Values of a are
a - 2 = 0
a = 2 .....(i)
a+3 = 0
a = -3 .....(ii)
1 min = 60 seconds
15 miles/sec * 1/60 = 0.25 miles/min
If 0.25 miles in 1 min,
then:
0.25 * 4 mins = 1 mile.
(I hope this is correct)
4:6:2
this is because 2+3+1 is 6 and you divide that by 12 which is 2 and you times 2 to every ratio
Answer:
53x - 4 = 30
53x = 30 +4
53x = 34
x= 34/53
I don't see a answer that matches the answer to the problem that you stated. Check problem.
Step-by-step explanation:
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
