Answer:
any of them work
Step-by-step explanation:
Pythagoren theorem states that a²+b²=c². If A is 8.5 and B is 11, you'd get
193.25=c²
Square root both sides to find out that the diagonal is 13.901 inches long
Answer: 4n^2
Step-by-step explanation: -3n^2 - (-7n^2) = -3n^2 + 7n^2= 4n^2. When adding and subtracting the exponents stay the same only the coefficients are subtracted or added
Answer:
Step-by-step explanation:
6(3x – 8) = 7(7x + 7)
18x - 48 = 49x + 49
49x - 18x = - 48 - 49
31x = - 97
x = - 97/31
