2/5+3/7 is the same as?

Vsevolod [243]

Answer:

29/35

Step-by-step explanation:

Least common denominator of 5 and 7 is 35

$\frac{2}{5}=\frac{2*7}{5*7}=\frac{14}{35}\\\\\frac{3}{7}=\frac{3*5}{7*5}=\frac{15}{35}\\\\\frac{2}{5}+\frac{3}{7}=\frac{14}{35}+\frac{15}{35}\\\\ \ = \frac{14+15}{35}\\\\ = \frac{29}{35}$

X^2+17x+72=12 PLEASE HELP QUICKLY THIS IS A TEST!!!! (Btw this is Plato)

FrozenT [24]

Answer:

x = -5 or x = -12

Step-by-step explanation:

x^2+17x+72=12

Subtract 12 from both sides.

x^2+17x+72-12 = 12-12

x^2+17x+60=0

Then factor the left side of the equation

(x+5)(x+12) = 0

Then set the factors equal to 0

(x+5)=0 or (x+12)=0

Therefore x=-5 or -12
