Answer:
D
Step-by-step explanation:
5 (x + 6) = 45
Multiply 5 by what's in parenthesis.
5 times x = 5x ** use the + sign ** 5 times 6 = 30
5x + 30 = 45
Add both of the volume of dirt,
50+25
75 cubic feet of dirt
Hope this helps.
Answer:
Step-by-step explanation:
f(1)=-11
f(n)=f(1)+d(n-1)
so d=22
f(n)=f(n-1)+22
Answer:
√2 is approximately 1.4.
Step-by-step explanation:
Part E:
1.3 squared is 1.69.
1.4 squared is 1.96.
1.5 squared is 2.25.
√2 is <em>not</em> between 1.3 and 1.4 because 1.4 squared only reaches up to 1.96 and not 2.
√2 <em>is</em> between 1.4 and 1.5 because 1.4 squared is 1.96 while 1.5 squared is 2.25. The √2 will be somewhere between 1.4 between 1.5.
2 is closer to 1.96 (0.04 units) than 2.25 (0.25 units). Thus, √2 is approximately 1.4.
