The perimeter of a rectangle is 40 cm. The length is 14 cm. Let x = width of the rectangle. Ravi says he can find the width usin

Usimov [2.4K]

Answer:

Divide both sides by 2

Step-by-step explanation:

We have the equation

2(x + 14) = 40

We divide both sides by 2

2(x + 14) = 40/2

x + 14 = 20

x = 20 - 14

x = 6

Therefore, the most helpful first step for solving Ravi's equation is: Divide both sides by 2

Which of the binominals below is a factor of this trinomial? x2-10x-39

Reika [66]

Answer:

Step-by-step explanation:

given x² - 10x - 39

since the coefficient of the x² term is 1

consider the factors of - 39 ( constant term ) which sum to give - 10 ( the coefficient of the x term )

The factors are - 13 and + 3, hence

x² - 10x - 39 = (x - 13)(x + 3) ← in factored form

Hence (x - 13) is a factor → b
