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 expression $9x^2+42x+49$ 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 $(3x+7) and (3x+7)$ .

Answer:

8.04 units

Step-by-step explanation:

By Pythagoras Theorem:

${x}^{2} = \bigg( \frac{25.2}{2} \bigg)^{2} - {(9.7)}^{2} \\ \\ {x}^{2} = ( 12.6)^{2} - {(9.7)}^{2} \\ \\ {x}^{2} = 64.67 \\ \\ x = \sqrt{64.67} \\ \\ x = 8.04176598 \\ \\ x \approx \: 8.04$
