Answer:
1
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 4-2)/(1 - -1)
= (4-2)/(1+1)
= 2/2
= 1
Perimeter of rec. = 2 ( l + w )
Given: perimeter of rectangle = 322m, length = 86m
Required: width = ?
Solution: 322 = 2 ( 86 + w )
Divide 322 by 2 ie, 322/2 = 86 + w
Will be equal to 161 = 86 + w
Therefore Width= 161 - 86 = 75
Answer:
3
Step-by-step explanation:
1. A - times a - equals a +, which means [-(-2)] equals (2)
2. 5- (2) equals 5 - 2
3. 5-2= 3
Answer:
a(n) = -351+8(n-1)
Step-by-step explanation:
This is an arithmetic sequence. Each new term is equal to the sum of the previous term and 8.
The expression you want is a(n) = -351+8(n-1)
