Answer: M=-7
Step-by-step explanation:
-2(m+6)+1=3
subtract 1 from both sides
-2(m+6)=2
divide by negative 2
m+6=-1
subtract 6 from both sides
m=-7
Answer:
c
Step-by-step explanation:
Divide using synthetic division, remembering to place a zero to denote the terms x³, x² and x
Since division by (x - 3) then evaluate using h = 3
3 | 1 0 0 0 7
↓
1 3 9 27 81
----------------------
1 3 9 27 88 ← degree 3 polynomial
quotient = x³ + 3x² + 9x + 27 , remainder = 88 → c
Answer: (a+2)(3a-16)
Explanation: In the photo. Let me know if you have any questions about what I did! :)
Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
