Let x = 3 and y = 2. Select from the drop-down menu to create a true statement.

5y2–2x < x2 +
A. y
B. x
C. xy
D.2y

Which expression completes the statement to form a true inequality?

3+62<

3³ + 12

5² + 4²

2³ + 5² + 6

2³ + 14 + 17

what level of math? also i don't need to be paid if i can you.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
