What is the coefficient in the expression x/3+7

I'm reading this as (x/3) + 7 that means the x and the 7 are separated by a plus sign. The coefficient is the number associated with any variable in the equation or expression.

Simply put in this case it is 1/3. It is not 3.

If you had something like 4x + 6y The coefficient for the x is 4 and the coefficient for the y is 6. When I was taking the stuff, they further said that the numerical coefficient was 4 for x and 6 for y. It's just a definition. Number with a variable.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
