I'm guessing the equation is 2x^2-3x=-5
If this is the case, then you need to set the equation to equal 0 by moving the -5 to the left side of it
2x^2-3x+5=0
The you can factor the equation
(2x-5)(x+1)=0
now solve for each factor
2x-5=0 is x=5/2x
x+1=0 is x=-1
1m =3.28 feet 1km= 1000m 1km=3 280 feet
120x3 280=393 600feet/h 1h=3 600sec
393 600/3 600=109.33feet/sec
Answer:
The answer to your question is:
Step-by-step explanation:
(4 + 5) + 2 = 4 + (5 + 2) Associative property of addition
2(2x + 4) = 4x + 8 Distributive property
( 7 x ) 3 = 7 (x 3) Associative property of multiplication
( 8 x 2) = (x 8 2) Commutative property of multiplication
( 7 + 3) + 1 = 1 + (7 + 3) Commutative property of addition
