Answer:
x=10 x=-2
Step-by-step explanation:
(x − 3)(x − 5) = 35
FOIL
x^2 -5x-3x+15 = 35
Combine like terms
x^2 -8x+15 = 35
Subtract 35 from each side
x^2 -8x+15-35 = 35-35
x^2 -8x-20 =0
Factor
What 2 numbers multiply to -20 and add to -8
-10*2 = -20
-10 +2 = -8
(x-10)(x+2) =0
Using the zero product property
x-10 =0 x+2 = 0
x=10 x=-2
5:3
5+3=8
8 units
800=8 units
divide oth sides by 8
100=1 units
soccer=5 units=5 times 100=500
social=3 units=3 times 100=300
500 soccer players
V = length×width ×height
V = 9 × 2 × 3
V = 54 units cubed
