Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
Exactly 1 day 3 hours and 30 minutes,or 27.5 hours
Answer:
Step-by-step explanation:
The equation of this circle is (x - 3)^2 + (y - 3)^2 = 12^2.
Let's substitute the coordinates of the given point and compare the results to the above equation: do they produce a correct statement?
(-6 - 3)^2 + (-5 - 3)^2 = ?
9^2 + 8^2 = 145
Because r = 12, the above result would need to be 144, not 145, if the given point were actually on the circle. We must conclude that (-6, -5) lies just outside the circle.
81 + 64 = 144
Answer:what is this
Step-by-step explanation:
bruh
Equation.
1/2 m - 3/4 n = 16
n = 18
Substitution.
1/2 m - 3/4(18) = 16
1/2 m - 13.5 = 16
1/2 m =16 +13.5
1/2 m = 29.5
m = 29.5 × 2
m = 59
