Answer:

6y^2+2y

Step by step explanation:

2y*(y+3)+4y*(y-1)

Distribute 2y through the parentheses

2y^2+6y+4y*(y-1)

Distribute 4y through the parentheses

2y^2+6y+4y^2-4y

Collect like terms

6y^2+6y-4y

Collect like terms

6y^2+2y

Answer:

6y² + 2y

Step-by-step explanation:

Use distributive property:a*(b+c) =a*b + a*c

2y(y + 3) + 4y(y -1) =2y*y + 2y*3 + 4y*y - 4y*1

                             = 2y² + 6y + 4y² - 4y

                             = 2y² + 4y² + 6y - 4y      {Combine like terms}

                             = 6y² + 2y

Solve for x. M=5/dx+e
snow_lady [41]

After solving  M=\frac{5}{dx}+e we get value of x:  x=\frac{5}{(M-e)d}

Step-by-step explanation:

We need to solve the equation M=\frac{5}{dx}+e to find value of x

Solving

M=\frac{5}{dx}+e

Adding -e on both sides

M-e=\frac{5}{dx}+e-e

M-e=\frac{5}{dx}

Multiply both sides by dx

dx(M-e)=5

Divide both sides by M-e

dx=\frac{5}{M-e}

Divide both sides by d

x=\frac{5}{(M-e)d}

So, After solving  M=\frac{5}{dx}+e we get value of x:  x=\frac{5}{(M-e)d}
