Answer:
200 miles
Step-by-step explanation:
40 x 5 = 200

a) <u>n² + 6 </u>
~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.
- If n = 1, first term = 1² + 6 = 7
- n = 2, second term = 10
- n = 3, third temm = 15
- n = 4, fourth term = 22
- n = 10, tenth term = 106
b) <u>3n²</u>
- If n = 1, first term = 3
- n = 2, second term = 12
- n = 3, third term = 27
- n = 4, fourth term = 48
- n = 10, tenth term = 300
Answer:
look below
Step-by-step explanation:
5d-6*(3cd) = 15cd^2-28cd
Those 3 lines are:
y=2x+2
X=4
Y=4
The R satisfies these:
Y<2x+2
X<4
Y<4
