How do you solve this? as you can see, i already found the but i need to know how to solve.

From what I am seeing, a "short" is a 1, and a "long" is an x.

So, you look at the side lengths.

The longer side length has two "longs" and three "shorts", so that is 2x + 3.

The shorter one has one "long" and one "short", which is x + 1.

Because those two are multiplied to create an area, the side lengths are multiplied. That gives us the answer you circled.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
