Which TWO systems of linear equations are solved correctly? A) If x + y = 3 and 2x + y = 12, then x = 9 and y = −6.
B) If 5x + y = 10 and x + 2y = 8, then x = 10 3 and y = 4 3 .
C) If x + y = 7 and 6x + y = 2, then x = 3 2 and y = 11 2 .
D) If 2x + 2y = 4 and x − 4y = 12, then x = 4 and y = −2.
E) If 2x − 4y = 4 and x − 6y = 10, then x = 2 and y = 2.

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

which expression represents the approximate length of bc?

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
