May you please tell me what is 9(2a+1)

18a + 9

Step-by-step explanation: So let's simplify this problem using the distributive property.

The first thing we want to do is distribute or multiply this 9 times each of the terms inside the set of parentheses.

So we get 9 times 2a + 9 times 1.

So we have 9 (2a) + 9 (1) and this simplifies to 18a + 9.

160

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.
