Hello! Combining like terms is just a fancy way of saying add all these numbers together. As long as numbers have the same variable (in this case x) and the same exponent (they don't have any in this case), you can add them together like normal. So! 3x + 5x +4x is the same as 3+5+4. Your simplified polynomial is 12x. Good luck with the math homework!
Answer:
the answer XxXxXxXxXx -YyYYYYY
Step-by-step explanation:
The answer to the question to <u>how many significant figures could the volume of the pyramid be reported</u> is B. 2 significant figures.
Since in multiplication, we cannot have more significant figures than the number with the least significant figures. So, the number of significant figures in our volume of the pyramid will be 2 since, the length of side of its square base measures 5.6 feet which is one significant figure less than that of its height which is 7.86 feet.
Since volume = area of base × height
volume = 5.6 × 5.6 × 7.86 ft³
So, the answer volume of the pyramid will have 2 significant figures.
The answer to the question to <u>how many significant figures could the volume of the pyramid be reported</u> is B. 2 significant figures.
