Answer:
D 28x+40
Step-by-step explanation:
To find the perimeter, we add all the sides
2x+2x+5x+8+4x+10+5x+8+x+2+2x+7x+12 = P
Combine like terms
2x+2x+5x+4x+5x+x+2x+7x+10+8+8+2+12
28x +40
X=30×6/4
x=45.
hope it helps
The solution will be:
<em><u>Explanation</u></em>
The given inequality is:
First we will subtract from both sides. So.....
Now we will subtract 13 from both sides. So.....
Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......
Thus, the solution will be:
Step 1 is wrong it should be: 2x - 3x - 1=3
The correct answer is {1, 2, 5, 6}.
A intersect B would be {3, 4}; the complement of this is everything else.
