2 m and 3 b can do a work in 8 days.

Then 3 m and 4 b do it in how many days.

=2*3*8=3*4*x

x=2*3*8/3*4

x=2*8/4

x=2*2

x=4 days

Simplify the following algebraic expression:<br> 4+3 [6z - 5(6 +2z)]

Tatiana [17]

$\huge\text{Hey there!}$

$\huge\text{4+3 [6z - 5(6 +2z)]}$

$\huge\text{4+(3)(6z)+(3)(-5(6+2z))}\\\\\rightarrow\huge\text{4+18z+(-30z)+(-90)}$

$\huge\text{\bf{Combine the like terms if you have any.}}$

$\huge\text{Like term \#1: 10z \& -30z}\\\\\\\huge\text{Like term \#2: 4 \& -90}$

$\huge\text{18z + (-30z) + (4 + (-90))}$

$\huge\text{18z + (-30z) = -12z}\\\\\\\huge\text{4 + (-90) = -86}$

$\boxed{\boxed{\huge\text{Answer: -12z + (-86)}}}\huge\checkmark$

<span>L = (0.8) T^2

T^2 = L / 0.8

T = sqrt{ L / 0.8 }

T = sqrt{ 30 / 0.8 }

T = sqrt{ 37.5 }

T = 6.1 seconds
