Answer:
-14
cuz sqrt of -16 is -4 and sqrt of -64 is -8 but there is an - sign there so it is positive
then 3+-4 is -1 and 6+8 is 14
lastly multiply and you get negative 14
Answer:
527 cubic meters
Step-by-step explanation:
The area of the cube would be 7.5^3 and the area of the rectangular prism would be 3.75*3.75*7.5. Then it would be 421.9 + 105.5 and rounded to the whole number the answer would be 527
1.20 + 0.34 = 1.54
That is the answer.
2*10^6 + 6*10^5 + 3*10^3 +9*10^1 +4*10^0
see expanded form is adding the digits together. and it would be what ever one number is times 10 to the power of how many digits are after that number. you skip the 0's though. hope this helps
