Answer:
-15
Step-by-step explanation:
-24 + (1-4)^2 (solve parentheses first)
= -24 + (-3)^2 (solve exponent)
= -24 + 9
= -15
Both of these values are the same, so the number sentence would state:
7.17 = 7.170
You can place any number of zeros to the very end on the right side (when there is a decimal point) without changing the value of the number.
7.1700000 = 7.17 also
97 rounds up to 100
78 rounds up to 80
100x80= 8,000
estimate=8,000
97x78=7,566
product=7,566
