Question

$$0.25(4x-3)0.05(10x-9)$$

Evaluate

$\frac{x^{2}}{2}-\frac{33x}{40}+0.3375$

Solution Steps

Multiply $0.25$ and $0.05$ to get $0.0125$.

$$0.0125\left(4x-3\right)\left(10x-9\right)$$

Use the distributive property to multiply $0.0125$ by $4x-3$.

$$\left(0.05x-0.0375\right)\left(10x-9\right)$$

Apply the distributive property by multiplying each term of $0.05x-0.0375$ by each term of $10x-9$.

$$0.5x^{2}-0.45x-0.375x+0.3375$$

Combine $-0.45x$ and $-0.375x$ to get $-0.825x$.

$$0.5x^{2}-0.825x+0.3375$$

Expand

$\frac{x^{2}}{2}-\frac{33x}{40}+0.3375$

Solution Steps

Multiply $0.25$ and $0.05$ to get $0.0125$.

$$0.0125\left(4x-3\right)\left(10x-9\right)$$
