Help! I really need some help on this. 1. Factor each of the following expressions.
a) x^2+9x+20
b)10n^2+n-3
c)2d^2-8de+6e^2

2. Juan is trying to factor x^2+7x+3 and makes the following table (in photo)
Juan concluded that x^2+7x+3 cannot be factored using integers.
a) Is Juan Correct?
b)Comment on Juan's strategy and improve his strategy if possible.

109 is the nearest whole number/final answer! : )

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.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
