Quickly compute the following differences of squares. (a). 64^2 − 14^2 (b). 112^2 − 88^2 (c). 785^2 − 215^2

VikaD [51]

Answer:

(a) 3900

(b) 4800

Step-by-step explanation:

We have given

(a) $64^2-14^2$

We know the algebraic equation $a^2-b^2=(a+b)(a-b)$

So $64^2-14^2=(64+14)(64-14)=3900$

(b) We know the algebraic equation $a^2-b^2=(a+b)(a-b)$

$112^-88^2=(112+88)(112-88)=4800$

$785^2-215^2=(785+215)(785-215)=570000$

Lauren, Rachel and Becca started a business over the summer. Their income was $500. The girls put in different amounts of work,

zloy xaker [14]

Answer:

Step-by-step explanation: total income=$500

Ratio of partition of money6:3:4

( Which gives that lauren gets 6x, rachel gets 3x and Becca gets 4x)

6x+3x+4x=500

13x=$500

X=500/13 ( transposition method)

x= 38.46

So lauren gets 6(38.46)… rachel gets 3(38.46)while Becca gets 4(38.46)…

Lauren= 230.76

Rachel=115.38

Becca= 153.84
