Answer:
7.2x - 4.8 > 24
<=>7.2x > 28.8
<=> x > 28.8/7.2
<=> x > 4
Step-by-step explanation:
Answer:
The answer is 2. x = 2
Step-by-step explanation:
2 x 2 + 1x = 6
2 x 2= 4
4 + 1x = 6
4 - 4 = 0
6 - 4 = 2
1x = 2
1x / 1 = 1 <--- This gets cancled out but leave the x.
2/ 1 = 2
x = 2
Answer:
4^3
Step-by-step explanation:
When you are multiplying exponents with the same base (for this problem the base is 4) you add together the exponents. It is kinda hard to explain but that is just a rule you can use. So, 4^(5+(-2))=4^3
X^2+11x+18<0 ----- Subtract 18 from both sides
(x+2)(x+9)=0-------- Factor the left side
------Set factors equal to zero
Your answer is -9<x<-2
