The equation given in the question is written below
- 3 + x^2 = - 19
x^2 = - 19 + 3
x^2 = - 16
x^2 = - (4)^2
Then
x = - 4
So we can see from the above deduction that x is equal to -4 and not +4. I hope the procedure is clear enough for you to understand. You can always use this method for solving problems of similar kind without requiring any help from outside. Only be careful about the calculation part of the problem given.
5 is the awser I'm pretty sure
Answer: 18
Step-by-step explanation:
subtract 5 - 7; since that's not possible make the 3 into a 2 and add a 1 in front of the 5; now do 15-7 = 8. 2-1 =1 ----> 18
Answer:
$56.25
Step-by-step explanation:
for every hour Dexter worked with his dad he made $12.50 since he worked with him 4.5 hours we have to multiply 12.50*4.5 or if easier add 12.5 four and a half time 12.5+12.5+12.5+12.5= 50 + 6.25 ( which is half of $12.50 because he only worked half an hour) = $56.25
