x = , x = 5

Step-by-step explanation:

Given

2x² - 11x + 5 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 5 = 10 and sum = - 11

The factors are - 1 and - 10

Use these factors to split the x- term

2x² - x - 10x + 5 = 0 ( factor the first/second and third/fourth terms )

x(2x - 1) - 5(2x - 1) = 0 ← factor out (2x - 1) from each term

(2x - 1)(x - 5) = 0

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x =

x - 5 = 0 ⇒ x = 5

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
