Answer:
D.(2,0) and (0,-4)
Step-by-step explanation:
A P E X approved.
It equals to:
(3(a+h)^2 - 3a^2) / h = 3(2ah+h^2) / h = 6a + 3h
So our equation to find this can be represented by 7x + 10 = 45.
(x representing miles run)
Just solve for x!
Subtract the 10 from both sides, you've got
7x = 35
And now to isolate the x, we divide both sides by 7.
Now we're left with just
x = 5!
We can check this by substituting 5 as x in our equation.
7x x 5 + 10 = 45
45 = 45
It's right!
So the runner ran 5 miles total.
Hope this helps!
If I skimmed over this too much, let me know and I'll try to explain the best that I can.
Answer: 150
Step-by-step explanation:
20 is 1/3 of 60. So you can just multiply 50x3 so the answer becomes 150.
Just use desmos to graph functions.
