Answer:

x = 2

Step-by-step explanation:

Firstly, calculate the area of the rectangle with the formula:

Length x width = area

(x+6) * 3 = 3x + 18

The formula for the area of a triangle is:

\frac{1}{2} * b * h

We can plug the known variables into the equation and get:

\frac{1}{2} * 8 * (x+4)

4 * (x + 4)

4(x + 4)

4x + 16

As the two areas are the same:

4x + 16 = 3x + 18

Subtract 3x from both sides of the equation:

4x + 16 - 3x = 3x + 18 - 3x

x + 16 = 18

Subtract 16 from both sides of the equation:

x + 16 - 16 = 18 - 16

x = 2

Hope this helps!

SVEN [57.7K]

Answer:

y = (7/3)x - 9

Step-by-step explanation:

1. Convert given equation to y=mx+b form --> y = (7/3)x - 5/3

2. Equation of new line --> y = (7/3)x + b

  • Note: 7/3 is the slope and for lines to be parallel they need the same slope so both equations have 7/3.

3. Plug in given values --> 5 = (7/3)(6) + b

4. Solve for b --> b = 5 - 14    b = -9

5. New line --> y = (7/3)x - 9

V=hpir^2

tricky, they didn't give us radius
they just gave circiufmerece

c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

subsitutet

v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches
