Solve DAb=sqrt{9^2+12^2}

$$D A b = \sqrt { 9 ^ { 2 } + 12 ^ { 2 } }$$

Solve for A

$$A=\frac{15}{Db}$$

$$b\neq 0\text{ and }D\neq 0$$

Steps for Solving Linear Equation

Calculate 9 to the power of 2 and get 81.

$$DAb=\sqrt{81+12^{2}}$$

Calculate 12 to the power of 2 and get 144.

$$DAb=\sqrt{81+144}$$

Add 81 and 144 to get 225.

$$DAb=\sqrt{225}$$

Calculate the square root of 225 and get 15.

$$DAb=15$$

The equation is in standard form.

$$DbA=15$$

Divide both sides by Db.

$$\frac{DbA}{Db}=\frac{15}{Db}$$

Dividing by Db undoes the multiplication by Db.

$$A=\frac{15}{Db}$$

Solve for D

$$D=\frac{15}{Ab}$$

$$b\neq 0\text{ and }A\neq 0$$

Steps for Solving Linear Equation

Calculate 9 to the power of 2 and get 81.

$$DAb=\sqrt{81+12^{2}}$$

Calculate 12 to the power of 2 and get 144.

$$DAb=\sqrt{81+144}$$

Add 81 and 144 to get 225.

$$DAb=\sqrt{225}$$

Calculate the square root of 225 and get 15.

$$DAb=15$$

The equation is in standard form.

$$AbD=15$$

Divide both sides by Ab.

$$\frac{AbD}{Ab}=\frac{15}{Ab}$$

Dividing by Ab undoes the multiplication by Ab.

$$D=\frac{15}{Ab}$$
