25-12=13 because if x=5 and y=12 just replace the letters with the numbers. Hope it helps mate
Answer: I think it’s 4
Step-by-step explanation: count the squares surrounding the triangle, 4 times 2 is eight 1/2 of that is 4
In this problem, we are asked to determine the degree of the given expression 12X4 - 8X + 4X2 -3. To answer this, first, we need to arrange the mathematical expression in descending order with respect to its power such as the new arrangement will become 12x4 + 4x2 -8x -3. The degree is clearly visible and it is 4. Therefore, the answer to this problem is the letter "B" which is 4.
