To solve x^2+ 5x= 0, Mai rewrote the equation as x(x+5) = 0. Explain how rewriting this equation in factored form enables Mai to solve the equation.

x=0

Step-by-step explanation:

i took the test

e) none of the above because the measure of angle cba is 101°

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
