Nonamiya [84]

Answer:

$.$

Step-by-step explanation:

<h2><u>IdEnTiTy UsED</u></h2>

${x}^{2} - {y}^{2} = (x + y)(x - y)$

1)

$(x - 5)(x - 5)$

=(x-5)²

2)

$(3x - 2)(3x + 2)$

${(3 x)}^{2} - {(2)}^{2}$

$= 9 {x}^{2} - 4$

3)

$(1+x)(1+x)$

= (1+x)²

Drag the tiles to the correct boxes to complete the pairs.

navik [9.2K]

A. 9

B. 24

C. 6

D. 16

Step-by-step explanation:

Given ratios are;

A. 2 : 3 = 6 : x

Product of mean = Product of extreme

$6*3=2*x\\18=2x\\2x=18$

Dividing both sides by 2

$\frac{2x}{2}=\frac{18}{2}\\x=9$

B. 4 : 7 = x : 42

Product of mean = Product of extreme

$7x=168$

Dividing both sides by 7

$\frac{7x}{7}=\frac{168}{7}\\x=24$

C. 2x : 48 = 3 : 12

Product of extreme = Product of mean

$2x*12=48*3\\24x=144$

Dividing both sides by 24

$\frac{24x}{24}=\frac{144}{24}\\x=6$

D. 12 : 15 = x : 20

Product of mean = Product of extreme

$15*x=12*20\\15x=240$

Dividing both sides by 15

$\frac{15x}{15}=\frac{240}{15}\\x=16$
