Use the algebra tiles to model the equation 2x + 4 = 3x + (-1). Then complete the sentences.

To model 2x + 4, you need:

___ positive x-tiles to represent 2x

___ positive unit tiles to represent 4.

To model 3x + (-1) you'll need:

3 ___ x-tiles to represent 3x.

1 _ unit tile to represent-1.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
