Mr. kelly uses an expression to represent the perimeter of a square, rewrite the expression to represent the length of a side of
the square. P=8x + 20
1 answer:
Answer:
therefore the side of the square is 2x + 5.
Step-by-step explanation:
i) let the side of the square be a
ii) therefore the perimeter of the square = 4a
iii) therefore 4a = 8x + 20
iv) therefore a = 2x + 5
therefore the side of the square is 2x + 5.

Answer:
Step-by-step explanation:
(3,4)=x1,y1 (5,8)=x2,y2. The slope is calculated using formula: Slope =y2−y1x2−x1. =8−45−3. =42. =2.
Answer:
500000N=2m
x. =6m
cross multiply, it'll be
6×50000÷2
=150,000N
