Mathematics

Vera_Pavlovna [14]3 years ago

Answer:

c = 5n

Step-by-step explanation:

each notebook is 5 dollars. so we multiply each notebook Carmen buys by 5 to find what she has to pay in total.

it's like if you eat 2 chocolates, and each contain 100 calories, you would be eating 200 calories total. the equation for that scenario would use the same logic:

totalCalories = 100*numberOfChocolates

since 100 is the number of calories in 1 chocolate.

Solve by completing the square
natima [27]

Answer:

see explanation

Step-by-step explanation:

Given

x² + 10x + 14 = - 7 ( subtract 14 from both sides )

x² + 10x = - 21

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 21 + 25

(x + 5)² = 4 ( take the square root of both sides )

x + 5 = ± 2 ( subtract 5 from both sides )

x = - 5 ± 2

x = - 5 - 2 = - 7, or x = - 5 + 2 = - 3

-------------------------------------------------

The equation can also be solved by factoring

x² + 10x + 14 = - 7 ( add 7 to both sides )

x² + 10x + 21 = 0 ← in standard form

(x + 7)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 3 = 0 ⇒ x = - 3
