<span>The approximate surface area is 153.86 square cm.</span>
Answer:
Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2
2x^2 + 3x - 20 = 0
(x + 4)(2x - 5) = 0
Solution:
x = -4
x = 5/2
Alright, here are the divisibility rules:
2 -- If the last digit is 0, 2, 4, 6, or 8.
3 -- If the sum of the digits is divisible by 3.
4 -- If the last two digits are divisible by 4.
5 -- If the last digit is 0 or 5.
6 -- If the number is divisible by 2 or 3.
7 -- Cross off the last digit, double it, and subtract. If new number is divisible by 7, the original number is divisible by 7.
8 -- If the last three digits are divisible by 8.
9 -- If the sum of the digits is divisible by 9.
10 -- If the last digit is 0.
11 -- Subtract the last digit from the number formed by the remaining digits. If new number is divisible by 11, the original number is divisible by 11.
12 -- If the number is divisible by 3 and 4.
Let's use these rules to answer your questions.

Well, that answers all of your questions! :)
graph each inequality y-3x<-4
First we solve the inequality for y
Add 3x on both sides, so inequality becomes
y < 3x -4
Now we graph it
for graphing , replace < symbol with = sign
y= 3x - 4
Now make a table, assume some number for x and find out y
x y
-1 y=3(-1)-4 = -7
0 y=3(0)-4 = -4
1 y=3(1)-4 = -1
Now plot (-1,-7), (0,-4) ,(1,-1) on graph
Join all the points and make a dotted line ( dotted line for < or > symbol)
now we do shading
for < symbol we shade down
for > symbol we shade up
The graph is attached below
