To solve this equation simply find 2 numbers that multiply to give -4 and add also to give 3, these numbers are 4 and -1. Since 4 • -1 = -4 and 4 + -1 = 3.
X^2 + 3x - 4 = 0
(X - 1)(X + 4) = 0
X = -4 and X = 1 in ascending order.
Answer:
x= 156

i had a test with the same question, i promise its right :)
Answer:
x= -17/11
Step-by-step explanation:
C
Because 1 km is 1,000 meters so you were just multiply 1000 by 10 and get 10,000
c:
Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
21/80 = .2625 * 100 is 26.25
The answer closest to this is 25%, so the answer is 25%
Hope this helped! :D
