B. <span>2x + 4 = 49
It is because a triangle has 2 sides and the question shows that 2 triangles equal the same so that becomes 2x. The third side is 4 so u add that to 2x which becomes 2x+4 and the perimeter equals 49 so basically the equation should be </span>2x + 4 = 49.
<u>ANOTHER EXPLANATION:
</u>The equation for perimeter is P=L+W
SO SUBSTITUTE ALL THE NUMBERS THAT ARE INCLUDED IN THE QUESTION AND THEN U CAN GET UR ANSWER.
We can divide 18 pounds by 2/3 pounds to find how many servings of meals the dogs will have.
We will use the keep change flip rule to solve this.
18 / 2/3 is then the same as 18 x 3/2
We then multiply across to get
54/2
This would be 27 meals that the food will last
2^(3-9)-11 =
1 step: subtract the 3 and 9 to get 6
(3-9)=6
2 step: multiply 2 to its self 6 times and
you should get 64
2*2=4*2=8*2=16*2=32*2=64
3 step: subtract 11 by 64 to get 53
64-11=53
hope I help if so hit the brainliest thanks
