Answer:

x - 2

Step-by-step explanation:

The expression can be factored using the factors of 14, 2 and 7, which add to give 9.

x² -9x +14 = (x -2)(x -7)

One of the factors is (x -2).

Answer:

x - 2

Step-by-step explanation:

To factorise the quadratic

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 7 and - 2, since

- 7 × - 2 = + 14 and - 7 - 2 = - 9, thus

x² - 9x + 14 = (x - 7)(x - 2) ← in factored form

Thus (x - 2) is a factor of the expression

If f(x)=5x^2 and g(x)=x+1 find (f•g)

LenKa [72]

(f•g)= f(1)•g(1)

= 5(1)^2 • (1)+1

= 5(1) • 2

= 5 • 2

= 10

Your answer here is 10.

zavuch27 [327]

Answer: 168 toads

Step-by-step explanation:

First we need to find the area of the garden. Area = length x width

Area = 12m x 7m = 84 m²

2 toads/ 1 sq m

84(2) = 168
