5 0

Answer:

D) 290

Step-by-step explanation:

w = 5

l = 12

h = 5

Formula:

SA = 2(wl + hl + hw)

SA = 2(5*12 + 12*5 + 5*5)

SA = 2(60 + 60 + 25)

SA = 2(145)

SA = 290

What is the correct factorization of 6x^2 -2x -20?<br> Please get correct!

Snezhnost [94]

→ 6x² - 2x - 20

→ 6x² + 10x - 12x - 20

→ x(6x + 10 ) - 2 (6x + 10)

→ (6x + 10) (x - 2) .

for

6x - 10 = 0

6x = 10

${x\:=\:\frac{5}{3}}\\$

for x - 2

x = 2
