y = 3x-2x∧2+5x∧3
When we replace x with value 3 we get
y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126
good luck!!!
Answer:
1500
Step-by-step explanation:
i typed it into a calculator
You divide both sides by -2. -15/-2=7.5
Negatives cancel so you get a positive. Positive numbers are obviously greater than -15 so it's greater than
The equation that can be used to determine the dimensions of the base of the doghouse is x² + 4x = 21
<h3>
What is the equation?</h3>
A quadratic equation is an equation that usually has a single variable and it is raised to the power of 2.
