10 4s times 4 = 40 times 4 = 160
It is: 4s = 64
If the length of each side is s, then you add the lengths of the sides: s+s+s+s = 4s Muliplication is easier: the perimeter is 4 times s = 4s.
Let F = father's age Let S = son's age F = 3S F - 5 = 4(S-5) F - 5 = 4S -20 F = 4S - 15 F = 3S 3S = 4S-15 S = 15, age of son
The perimeter of a square is equal to 4 times the value of one side. So P = 4s 24 = 4s 24/4 = 4s/4 6= s The length of one side is 6 meters.
They are 4's.
Equation 1. f = 13sEquation 2. f + 9 = 4(s + 9) ie f + 9 = 4s + 36 ie f = 4s + 27Substitute for f: 13s = 4s + 27Subtract 4s from each side: 9s = 27Divide each side by 9: s = 3 so f = 39 ( in 9 years s = 12, f = 48)
s2 + 4s - 32 = 0 What two factor of - 32 add up to 4? (s - 4)(s + 8) s = 4 ===
8/4 = 2 There are two 4s in 8.
since A=4S then S=A/4 A is not 4S. The perimeter P is 4S. The area is S multiplied by S or S squared. therefore the side of a square is the square root of the area.
4 wheel drive S power.
you can not. and it's not 4 4's its 4 4s I found with 3 fours : ALOG10(SQRT(4))-4/4
