I don't know all 12, but I can tell you some.
1. Shade the side of the line that satisfies the inequality.
2. If the inequality sign has an "or equal to" line under it, make the line on the graph connected.
3. If the inequality sign does not have an "or equal to" line under it, make the line on the graph dashed.
4. Isolate y (or the variable that is being used), and keep it on the left side of the inequality.
Answer:
(x + 8) • (x + 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2+15x+56
The first term is, x2 its coefficient is 1 .
The middle term is, +15x its coefficient is 15 .
The last term, "the constant", is +56
Step-1 : Multiply the coefficient of the first term by the constant 1 • 56 = 56
Step-2 : Find two factors of 56 whose sum equals the coefficient of the middle term, which is 15 .
-56 + -1 = -57
-28 + -2 = -30
-14 + -4 = -18
-8 + -7 = -15
-7 + -8 = -15
-4 + -14 = -18
-2 + -28 = -30
-1 + -56 = -57
1 + 56 = 57
2 + 28 = 30
4 + 14 = 18
7 + 8 = 15 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 7 and 8
x2 + 7x + 8x + 56
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+7)
Add up the last 2 terms, pulling out common factors :
8 • (x+7)
Step-5 : Add up the four terms of step 4 :
(x+8) • (x+7)
Which is the desired factorization
Final result :
(x + 8) • (x + 7)

Answer:
area=length*breadth
area=24*40
area=960sqare m
if we convert 960m to mm it will be 960000mm
final answer area=960000 square mm
4.3 I believe. That's the answer I got.
The answer is 6x to the power of 2 +48x
