Answer: 15

Step-by-step explanation:

I think the answer is correct because, The aformula of a parellelogram is base times height. Since we see 5 is the base and 3 is the height all we have to do is multiply 5 times 3 and that equals 15. To make sure we are correct you can divide 15 by 5 or 3 and you would still get a number in the equation.

Hope This Helps!

I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)

First one: 3x+9+8x + 12

Collect like terms and simplify

(3x+8x)+(9+12)

11x+21

Second one: 2x + 6+x² + 6x + 9

Collect like terms and simplify

$(2x+6x)+(6+9)+x^{2}$
