Answer:Depending on how high u do it either by 0,25,50 or 0,50,100
Step-by-step explanation:
Answer:
x < -20
Step-by-step explanation:
x / -4 + 14 >20
Subtract 14 from each side
x / -4 +14-14 > 20 -14
x / -4 > 6
Multiply each side by -4, remembering to flip the inequality
x / -4 * -4 < 6 * -4
x < -20
The answer would be 4c^2+8c+3
The arrow stands for squared off you didn’t already know but these are very easy to solve because you just multiply it out
