Let the original length of the square be x cm.
(x+5) X (x-2) = 60
Or, x^2-2x+5x-10-60 = 0
Or, x^2+3x-70=0
Or, x^2+10x-7x-70=0
Or, x(x+10)-7(x+10)=0
Or, (x-7)(x+10)=0
Therefore, x=7 or x=-10 (rejected as the length cannot be negative)
Ans: Area of the square=l^2=7^2=49 square meters.
Answer:
IQR = 157.5
Step-by-step explanation:
Q1 = 518.5
Q3 = 676
Equation = 676 - 518.5 = 157.5
Hope this helps!
3*4=12
2x*4=8x
So,answer is 8x+12
300 - 3x = 24
-24 -24
276 - 3x = 0
+3x +3x
276 = 3x
276/3 = 3x/3
92 = x
x = 92
