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.
Answer:

Step-by-step explanation:
b. 450.80
you multiply 40 x 9.80 ...equals 392.
<span>take 1/2 of 9.80...that equals 4.90. </span>
<span>4.90 plus 9.80 equals $14.70 x 4 = 58.80 </span>
<span>$58.80 plus 392. equals $450.80</span>
