Question

find the value of x if
13 X = 58 whole square minus 45 whole square​

Answer 1

Answer:

103

Step-by-step explanation:

13x= (58)²-(45)²

13x= (50+8)²-(50-5)²

13x= (a+b)²-(a-b)²

13x= (50²+ 8² +2*50*8)-(50²+5²-2*50*5)

13x= 2500 +64 +800 -2500 -25 +500

13x= 64+800 -25+500

13x= 39 +1300

13x=1339

x=1339/13

x=103
