-3(x+4) what’s the answer to this?

-3x-12

Step-by-step explanation:

This is a problem of distribution.

Distribute means to multiply the variable outside the perenthesis to what's inside the perenthesis.

What you are going to do is distribute the -3 to the x and 4

-3 times x is -3x

-3 times 4 is -12

Make sure the signs are correct and the new expression is -3x-12

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.
