Answer:

h = \dfrac{A - 9}{6}

Step-by-step explanation:

A=b^2+2bh

b = 3

A = 3^2 + 2(3)h

A = 9 + 6h

6h = A - 9

h = \dfrac{A - 9}{6}

Infinite Algebra 2
Irina-Kira [14]
The first problem, all you need to do is combine like terms then isolate the n:
4n-2n=4
~subtract 2n from 4n (2n)
2n=4
~then divide both sides of the equation by 2 to isolate the n
n=4

The second problem follows the same steps of combining like terms and isolating the variable. Here, you'll have to combine 2 like terms:
-12=2+5v+2v
~first combine the variables which is just 5v+2v which is 7v
-12=2+7v
~then subtract 2 from both sides to isolate the 7v
-14=7v
~then divide both sides by 7 to isolate the v and get your answer
-2=v

Hope that helped!

X(5)+2=244<br>help pls<br>(^_^)​
arsen [322]

Simplify both sides of the equation

  • 5x+2=244

Subtract 2 from both sides

  • 5x+2−2=244−2
  • 5x=242

Divide both sides by 5

\frac{5x}{5}  =  \frac{242}{5}

  • Answer

\: x =  \dfrac{242}{5}

OR

\: x =  48.4
