Answer: The total change is 21.
Since you want to find the change from the lowest to highest, make it into a subtraction problem. First of all, take the smallest number in front of the largest.
20 -1
Next, add a minus sign in between, your equation should look like this:
20 - (-1) = x
Then, you cancel out the negative signs. After that you solve it
20 - (-1) -> 20 + 1.
Lastly, you add them together.
20 + 1 = 21.
In conclusion, the answer is 21.
54 because the formula for the area of triangle is 1/2bh so you just substitute the b and h for 18 and 6
Answer:
-16t² + 13.4t + 120
= ( t-3.189)(t+2.352)
t = 3.189s or t = -2.352s (ignore)
ignore -2.352s because time cannot be in negative form
