yes it is...21x4= 84
21 21 because 21x4=84
The multiples of 21 up to 500 are as follows: 21x1=21 21x2=42 21x3=63 21x4=84 21x5=105 21x6=126 21x7=147 21x8=168 21x9=189 21x10=210 21x11=231 21x12=252 21x13=273 21x14=294 21x15=315 21x16=336 21x17=357 21x18=378 21x19=399 21x20=420 21x21=441 21x22=462 21x23=483 21x24=504
Well, isn't that a happy little math problem we have here! If we take 21 and multiply it by 4, we get 84. Just imagine all the possibilities and beauty that number can bring into your world. Remember, there are no mistakes in math, just happy little accidents.
the four times table is incredibly easy! ill tell you them up to 26 1x4=4 2x4=8 3x4=12 4x4=16 5x4=20 6x4=24 7x4=28 8x4=32 9x4=36 10x4=40 11x4=44 12x4=48 13x4=52 14x4=56 15x4=60 16x4=64 17x4=68 18x4=72 19x4=76 20x4=80 21x4=84 22x4=88 23x4=92 24x4=96 25x4=100 26x4=104 i could go on and on. hope this helps!

7x(3x3 - 2x2 + 5x + 1)

Assuming the use of BODMAS, (5 x 2) + (21 x 4) = 10 + 84 = 94

A hand equals 4 inches, so 19 x 4 = 76". 76" divided by 12 = 6 foot 6 inches.
