You substitute M for 3 and C for 6. So you get E = (3)(6)(2) which equals 36.

All you have to do is substitute the M and C value's into the equation.

E = MC2

E = (3)(6)(2)

E = 36

Hope your thanksgiving goes well! Here's a turkey!

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

loris [4]

Answer:

x = $\frac{86}{179}$

Step-by-step explanation:

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

Multiply both sides by 10:

7.4x×10+4.1(2x-4)×10=-2.3(x-6)×10-21.6×10

Refine:

74x+41(2x-4)=-23(x-6)-216

Distributive Property:

74x+82x-164=-23(x-6)-216

Combine like terms:

156x-164=-23(x-6)-216

Distributive Property:

156x-164=-23x+138-216

Combine like terms:

156x-164=-23x-78

Add 164 to both sides:

156x-164+164=-23x-78+164

Simplify:

156x=-23x+86

Add 23x to both sides:

156x+23x=-23x+86+23x

Simplify:

179x=86

Divide both sides by 179:

$\frac{179x}{179}$ = $\frac{86}{179}$

Simplify:

x = $\frac{86}{179}$

The answer to the length of x is in mm. please help!

romanna [79]

Answer:

3.69 mm

Step-by-step explanation:

So it's a right triangle so you can use a^2+b^2=c^2

Plugging in what we know the equation becomes:

2.8^2+2.4^2=c^2 (C = x because x is the hypotenuse)

7.84+5.76=c^2

13.6=c^2

The square root of 3.68782 which rounds to 3.69

So x=3.69mm
