Answer:

x = -8/3 = -2.667

x = -7/3 = -2.333

Step-by-step explanation:

Equation at the end of step 1 :

(((3x + 5)2) + 5 • (3x + 5)) + 6 = 0

Step 2 :

Trying to factor by splitting the middle term

2.1 Factoring 9x2+45x+56

The first term is, 9x2 its coefficient is 9 .

The middle term is, +45x its coefficient is 45 .

The last term, "the constant", is +56

Step-1 : Multiply the coefficient of the first term by the constant 9 • 56 = 504

Step-2 : Find two factors of 504 whose sum equals the coefficient of the middle term, which is 45 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 21 and 24

9x2 + 21x + 24x + 56

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (3x+7)

Add up the last 2 terms, pulling out common factors :

8 • (3x+7)

Step-5 : Add up the four terms of step 4 :

(3x+8) • (3x+7)

Which is the desired factorization

Solve : 3x+7 = 0

Subtract 7 from both sides of the equation :

3x = -7

Divide both sides of the equation by 3:

x = -7/3 = -2.333

Solving a Single Variable Equation :

3.3 Solve : 3x+8 = 0

Subtract 8 from both sides of the equation :

3x = -8

Divide both sides of the equation by 3:

x = -8/3 = -2.667

Jill's mom made 4 pies for dessert for the week. Jill wants to bring a slice of pie to school everyday for the next 10 days. If she wants to eat the same amount of pie every day, how much pie should she bring for lunch each day?

Answers

Answer:

2/5

Step-by-step explanation:

Jill wants to eat the same amount of pie every day so we need to divide the amount of pie by the amount of time. This gives us 4/10 which simplifies to 2/5. She should bring 2/5 a pie each day.
