Alicia is programming computerized robotic arms to cut burlap for the 4th of July placemats. The placemats are to be rectangular in shape with an area represented by
45x^2 - 71x- 150. The width of each placemat is represented by 5x + 6. The
expression to represent the length of each placemat can be determined by the
formula, length = area divided width. Which expression can Alicia use in the programming
to represent the length of each placemat?
F9x - 25
G 9x + 25
H 45x^2-66x144
J 9x^2-14.2x-30

hey i’m new i won’t be answering any questions now bye peeps see you next time

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
