The 1st stage: x, the 2nd stage: y.
x + y = 152
x = y + 28
y + 28 + y = 152
2 y = 152 - 28
2 y = 124
y = 124 : 2 = 62
x = 62 + 28 = 90
Answer: the first stage burns 90 seconds and the second burns 62 seconds.

Answer:
When one shape can become another using only Turns, Flips and/or Slides, then the two shapes are Congruent. Two shapes are Similar when we need to Resize for one shape to become another (we may also Turn, Flip and/or Slide). So, when one shape can become another using transformation, the two shapes might be Congruent or just Similar?
Step-by-step explanation:
The answer is m^3
When multiplying the same base with an exponent (m), you add the exponents together.
In this case, it would be m^3+0, which equals m^3
That’s your answer
Also, just a reminder:
Anything to the power of 0 is equal to 1,
For example, 5^0 = 1
