<span>We know that the surface of a sphere is: S = 4 * pi * r^2 The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51 And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32 So the surface of Jupiter is around 11^2 times bigger than the Earth</span>

Factor completely 9x2 42x 49. (3x 7)(3x − 7) (9x − 7)(9x − 7) (3x 7)(3x 7) (9x 7)(9x 7).
sweet-ann [11.9K]

Factors of the given expression by splitting middle term of expression9x^2+42x+49 will be (3x+7) and (3x+7).

Given expression is

9x^2+42x+49

<h3>What is a factor?</h3>

A factor is a number that divides another number leaving no remainder

After we split 42x into 21x each,

The expression looks like,

9x^2+21x+21x+49

3x(3x+7)+7(3x+7)\\

Taking 3x+7 as common

(3x+7) (3x+7)

So factors will be (3x+7) and (3x+7).

Therefore,

Factors of the given expression 9x^2+42x+49 will be (3x+7) and (3x+7).
