9x+2=8x2+6x negative 8 x squared + 3 x + 2 = 0. x = startfraction negative 3 plus-or-minus startroot (3) squared minus (4) (negative 8) (2) endroot over negative 16 endfraction. x = startfraction negative 3 plus-or-minus startroot 9 minus (64) endroot over negative 16 endfraction. x = startfraction 3 plus-or-minus startroot 55 endroot i over 16 endfraction.

step-by-step explanation:

mean or average is 40.6

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

30,40,50 is correct answer
