HELP PLS ITS FORR A TEST

c ≈ -6.3, 6.3

n^2 = 40

Square root both sides to find n.

n = √40

Convert √40 to a number using a calculator. This can be positive or negative.

-√40 = -6.32455532

√40 = 6.32455532

Round to the nearest tenth by looking at the value to it's right (the second digit after the decimal place) and rounding up if it's greater than or equal to 5.

-√40 = -6.32455532

√40 = 6.32455532

2 < 5, so we leave it as it is.

c ≈ -6.3, 6.3

i hope this helps :))

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.
