Fthe quadratic formula is used to solve 2x 2 = 8x - 3, what are the solutions?

x = 2 ± √10

express the equation in standard form : ax² + bx + c = 0 ( a ≠ 0 )

then x = ( - b ±√( b² - 4ac) ) / 2a

given 2x² = 8x - 3, then

2x² - 8x + 3 = 0 ( in standard form )

with a = 2, b = - 8, c = 3

x = (8 ±√(64 - 24) )/4 = (8 ±√40) / 4 = (8 ± 2√10) / 4

x = 2 ± √10

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
