(2x - 3) (3x + 4) = 6x² + 8x - 9x - 12 = <u>6x² - x - 12 </u>
The answer is D because side 3 is to far from side 1 and side 2 because you cant make a triangle out of those measurements
Here's a tip
if the sum of side 1 and side 2 are greater than side 3 then it forms a triangle
3,500 g=3,500 g * (1 Kg / 1000 g)=3.5 Kg.
answer: 3,500 g=3.5 Kg

Diagonals of a rectangle are congruent.
18x - 28 = x + 380
Solving for x, I get 17.
So, x = 17.
PR = 18x - 28
PR = 18(17) - 28
PR = 278
QS = x + 380
QS = 17 + 380
QS = 397
