In a group consisting of 8727 randomly selected people, estimate how many more people can correctly spell weird than inoculate.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

it would be 6xy and -16xy.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
