Solve 1800=0*30+1/2*x*30^2

$$1800=0 \times 30+ \frac{ 1 }{ 2 } \times x \times { 30 }^{ 2 }$$

Solve for x

$$x=4$$

Steps for Solving Linear Equation

Multiply 0 and 30 to get 0.

$$1800=0+\frac{1}{2}x\times 30^{2}$$

Calculate 30 to the power of 2 and get 900.

$$1800=0+\frac{1}{2}x\times 900$$

Multiply \frac{1}{2} and 900 to get \frac{900}{2}.

$$1800=0+\frac{900}{2}x$$

Divide 900 by 2 to get 450.

$$1800=0+450x$$

Anything plus zero gives itself.

$$1800=450x$$

Swap sides so that all variable terms are on the left hand side.

$$450x=1800$$

Divide both sides by 450.

$$x=\frac{1800}{450}$$

Divide 1800 by 450 to get 4.

$$x=4$$
