17.2*40 = 17.2*(10*4) since 40 = 10*4
=(17.2*10)*4 by the associative rule for multiplication
= 172 *4
=(100+70+2)*4
= 400+280+8
= 688
172 - 40% = 172 x (1 - (40/100)) = 172 x 0.6 = 103.2
It is 6.88*104
Yes 4 x 40 = 160 leaving 12 which is 4 x 3 172 / 4 = 43
2 x 2 x 43 = 172
yes
x = 172 + 4 Therefore, x = 176
x = tan(phi)
116 x 172 what? Inches, miles, hours?
It is 3080.
172 x 84 = 14,448
172 x 78 = 13416
1 x 172, 2 x 86, 4 x 43
