Answer:
m<W: 23
Step-by-step explanation:
8x - 9 + 30x - 4 + 13x - 11 = 180
51x - 24 = 180
51x = 204
x = 4
m<W:
8x - 9
8(4) - 9
32 - 9
23
Answer:

Step-by-step explanation:
Let the number be x;
The product of 4 and the number will be;

The the square of the number is given as;

Taking the difference of both expressions above;

Factor out the common term:

Hence the difference between the product of 4 and a number and the square of the number is 
Answer: For -6+14<-28, the answer is....
Inequality form : x>7
For 9x+15<-=12, the answer is...
Inequality form : x <= -3
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable. (THIS IS FOR BOTH ANSWERS!!)
