@RHSTUDYZONE Ans: 52 m
Soln: 2x+3= sqrt(169sqm); 2x+3=13
Perimeter: 4S= 4(2x+3)=4(13)=52 m

[Princess Katelynn @PrincessKetket]

@mathtech789 Ans: 7 and -5
Soln: a= +/-6
On a=+6: 6+6/6= 7
On a=-6: -6+ (-6/-6)= -5

@IQTestBrain Ans: 346.40m
Using Sine Law: a/sinA = b/sinB

@Muhammetmsic Ans: +12 and -12
Soln: A=20/B; 20/B -B=8;
20-B^2 /B =8; B^2+8B-20=0
Factors: (B+10) (B-2)=0; B=-10; B=2
On B=-10: A-(-10)= 8; A= -2
On B=2: A-2=8; A=10
Hence: A=-2; B= -10; A+B = -12
A=10; B=2; A+B = 12

@MATHSWITHZIA Ans: 5sqrt2 and -5sqrt2
Soln: M=+/- 10; N= 2sqrt2
On M=+10: 20/2sqrt2= 10/sqrt2 = 5sqrt2
On M=-10: -20/2sqrt2=-10/sqrt2= -5sqrt2

@UchennaF28384 Ans:30
Soln: 1/2 = 15/m; m=15×2=30

[Princess Katelynn @PrincessKetket]

@mathtech789 Ans: 98%
Soln: 100÷25×24=96

[Princess Katelynn @PrincessKetket]

@IQTestBrain Ans: undetermined
Zero divided by any number is 0, but any number divided by zero is undetermined. Since both are 0 the answer is undetermined.
