Answer:
Teo is 6 and Richard is 23
formula = height = 12+10t
where t = number of weeks
so for t10
height = 12+10(10) = 12+100 = 112 cm
for t12
height = 12+10(12) = 12 +120 = 132 cm
So
(x-4)^2=(x-4)(x-4)=x^2-4x-4x+16=x^2-8x+16
Answer:
approximately 9 weeks
Step-by-step explanation:
I can't really show the work on here, 1,000,000÷15,000= 66. (a whole lot of numbers, but only 66 is important). There is 7 days in a week, so 66 days ÷7 equals 9.(again a whole lot of useless numbers).
