This question seems to me to be an exercise in applying the rule for a difference of squares in order to rewrite the difference of two relatively large numbers as the "simpler" product of other integers.
question 6 - if the area is 144 then one side is 12ft as the square root of 144 is 12
I used math
anyway
remember you can do anything to an equation as long as you do it to both sides
so
4n+2 and 1/2=2n+5
minus 2n both sides
4n-2n+2 and 1/2=2n-2n+5
2n+2 and 1/2=0+5
2n+2 and 1/2=5
minus 2 and 1/2 both sides
2n=2 and 1/2
divide both sides by 2
I mean times both sides by 1/2
n=1 and 1/4
answer is C
Answer:
Step-by-step explanation:
Let y represent the sumo wrestler's weight (in kilograms) after x months.
When he started his diet, he weighed 79.5 kilograms, this means x = 0 months, y = 79.5 kg. So, y-intercept is at point (0, 79.5).
He gained weight at a rate of 5.5 kilograms per month, so the slope of the linear function is 5.5.
Hence the equation of the linear function in the slope-intercept form is
The graph of this function is attached.
