Answer:

$\frac{-5}{3}$

Step-by-step explanation:

3(2 + 4x) = -7 x 2 Distribute the 3

6 + 12x = -14 Subtract 6 from both sides of the equation

12x = -20 Divide both sides by 12

x = $\frac{-20}{12}$ Divide the top and the bottom of the fraction by 4

x = $\frac{-5}{3}$

Use the substitution method to solve the system of equation.choose the correct ordered pair. 2

Jlenok [28]

I’m not sure if the 2 is counted in the equation or not

Since x=4, substitute it for x in the other equation

4+3y=29
3y=25
Y=8.333333333

2(4)+3y=29
8+3y=29
3y=37
y=12.33333333

Answer:

$230.73m^2$

Step-by-step explanation:

$A=2a^2+4ah=2*4^2+4*4*4=96m^2$ (square prism)

$A=2\pi rh+2\pi r^2=2*\pi *4*9+2*\pi *4^2 = 326.73m^$ (cylinder)

$326.73-96=230.73m^2$ ( $\frac{3}{4}$ cylinder)
