Step-by-step explanation:
x^2-10x+21
(x-7)(x-3)
find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10
<span> A toy jeep is 12 1/2 inches
Actual jeep is 18 ¾ feet long
before we determine the ratio, let’s convert first each size into the same unit
of measure and decimal points
=> 12 ½ = 25/2
=> 12.5 inches
=> 18 ¾ = 75/4
=> 18.75 feet
Now, let’s convert feet to inches to know the ratio
=> 1 foot = 12 inches
=> 12.5 inches : 225 inches
=> 225 / 12.5
=> 18 inches
thus in every 1 inch of toy car represents 1.5 feet of actual car.

Given that the first mass of the duck is 0.05 kg and it gains weight at a rate of 0.042 kg/week, the equation that would represent this scenario is,
y = 0.05 + 0.042x
where y is weight and x is the number of weeks. To determine the number of weeks in which the duck's mass becomes 0.890,
0.890 = 0.05 + 0.042x
The value of x from the equation is 20.
