Answer:
The evaluated answer to this equation is 19.
Step-by-step explanation:
<em>2r² + 3s³ - r² + 4t² - r²</em>
In the problem, we are given values for the variables in the equation.
<em>r = -2</em>
<em>s = -3</em>
<em>t = 5</em>
Let's plug these numbers into the equation.
<em>2(-2)² + 3(-3)³ - (-2)² + 4(5)² - (-2)²</em>
First, simplify the exponents.
<em>2(4) + 3(-27) - (4) + 4(25) - (4)</em>
Next, multiply the numbers starting from left to right.
<em>8 + (-81) - 4 + 100 - 4</em>
Add 8 and -81 together.
<em>-73 - 4 + 100 - 4</em>
Subtract 4 from -73.
<em>-77 + 100 - 4</em>
Add -77 to 100.
<em>23 - 4</em>
Subtract 4 from 23.
<em>19 </em>
<u>So, your final simplified answer to this equation is 19.</u>
