For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21
Answer:
B. g is Greater or equal to 64
Answer:
108 square feet
Step-by-step explanation:
First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.
Answer:
(-2,8) and (2,-8)
the second is a reflection across the x axis
the third is a reflection across the y axis
this just reverse the points, i'm not sure if it's anything
Step-by-step explanation:
Answer:
24.
Step-by-step explanation:
Let's make the answer a variable, alright?
20 = (x - 3)/3 + 3(x + 2)
Get rid of the fractions.
120 = 2(x-3) + 3(x + 2)
120 = 2x - 6 + 3x + 6
120 = 5x
x = 24.
24 is your answer.
