Classify the following polynomials. Combine any like terms first. x²+ 3x + 2x – 2x² x³+ 4x – 4x – 4x² x³+ 2x – x³ – 2x² + 3

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

b. f(x) = –√x + 3this is the correct answer

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
