8 × 25 × 23 = 4,600
The answer is 4,600.
Answer:
Create a triangle with the 3-, 4-, and 5-inch sticks and measure the angles to show that one angle is a right angle.
Step-by-step explanation:
Answer:
Use the quadratic formula

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
