1/2 (b - 10) + 2b = 25
Serggg [28]

Answer:

the answer is 12

Step-by-step explanation:

Simplify both sides of the equation.

12(b−10)+2b=25

(12)(b)+(12)(−10)+2b=25(Distribute)

12b+−5+2b=25

(12b+2b)+(−5)=25 (Combine Like Terms)

52b+−5=25

52b−5=25

add 5 to both sides.

52b−5+5=25+5

52b=30

multiply both sides by 2/5.

(25)*(52b)=(25)*(30)

b=12

Find all roots: x^3 + 7x^2 + 12x = 0<br> Show all work and check your answer.
enot [183]

Answer:

x=0,x=-4,x=-3

Step-by-step explanation:

The given equation is

x^3 + 7x^2 + 12x = 0

Factoring by x:

(x^2 + 7x + 12)x = 0

One of the root is x=0. Let's solve the parentheses.

Expanding the trinomial

x^2 + 4x+3x + 12=0

Factoring

x(x + 4)+3(x + 4)=0

Factoring

(x + 4)(x+3)=0

This will give us the two remaining roots

x=-4,x=-3
