Perimeter is 20 and the area is 25
$520 was earned by carl in last week
Step-by-step explanation:
(1/2 X - 20 ) = 240
1/2 X = 240 +20 = 260
X = 260÷1/2 = 520
verification
520 ÷2 = 260 - 20 = 240
Hence proved
17ft 8in = 212 in so according to the options I would say go with 165 so A.
The relationship between the sides of the polygon and the triangle follows an arithmetic sequence
The expression that represents the number of triangles is (c) n - 2
From the diagrams, we have:
Sides Triangles
5 3
6 4
8 6
The above can be represented as functions as follows:
Express 6 as 8 - 2
Express 8 as n
So, the expression that represents the number of triangles is (c) n - 2
