Answer:
C (both)
step by step explanation:
$30+$25(x)=$180
U can solve by isolating da variable. Subtract 30 on both sides. Given u:
$25(x)=$150
Now u divide 25 to both sides. Given u:
x=6 days
Answer:B
Step-by-step explanation: I can’t because I can’t explain things sorry
If the width = x m then the length = 2x - 4 m
Area = x(2x - 4) = 70
2x^2 - 4x - 70 = 0
2x^2 - 14x + 10x - 70 = 0
2x(x - 7) + 10(x - 7) = 0
(2x + 10)(x - 7) = 0
x = 7 or -5 ( ignore negative)
width = 7 m and length = 10 m answer
Subtracting a negative number is like removing debt. When you remove debt, you effectively gave someone money and the value of their bank account increased.
Another answer is that “subtraction is addition of the opposite,” so subtracting a negative number is really adding a positive number, which again causes the other number to increase.
