Answer:
19
Step-by-step explanation:
70 - 51 = 19
To check:
19 + 51 = 70
x is timed by .5 in the first one (A) which would make it the linear function.
Answer:
by sum and product method for quadratic equation.
<span>1800 = -3p^2+70p+988
0 = -3p^2+70p - 812
Using the discriminant means taking the section of the quadratic formula:
âšâ€‹(b^2)â’4ac
And by plugging in the values of our formula we get:
âšâ€‹(70^2)â’4*-3*-812
Which yields:
âšâ€‹4900 â’ 9744
Since this is a square root of a negative number, it says there is no real solution for the formula, which makes sense because the formula is a quadratic that is pointing downwards (a = -3p^2) and underneath the number line (c = -812).

Answer:
n = 5
Step-by-step explanation:
First, you'd want to expand the entire equation to solve it.
4 (2n + 5) = 60
8n + 20 = 60
8n = 40
n = 5
I hope this helped!
