I think 7 bags do 31.5 m squared
68 degrees because 56×2=112 then 180-112=68
Answer:
2. power
4. tenth
20. hundred-thousandth
40. 5.063
50. 67/10
Step-by-step explanation:
20. If the underlined digit is the zero, the answer is "hundred-thousandth." It's hard to tell from the picture if zero is the underlined digit.
40. 5 and 63/1000 = 5 + 63/1000 = 5 + 0.063 = 5.063
50. 6.700 = 6700/1000 = 67/10
Answer:
Step-by-step explanation:
Use identity : (a + b)² =a² + 2ab + b²
49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²
= (7m²)² + 2 *7m²*10 + 10²
= (7m² + 10)²
= (7m² + 10)(7m² + 10)
