What is y+5=7(x-8) written in standard form?

Step-by-step explanation:

This is a linear function.  Standard form for a linear function is

Ax + By = C

Begin by distributing to get rid of the parenthesis:

y + 5 = 7x - 56

Now combine the constants on the right side:

y = 7x -61  That's slope-intercept form, but to get it into standard, move the 7x over to the y side:

-7x + y = -61

If you don't like to lead with a negative, you can simply just change ALL the signs:

7x - y = 61

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.
