The answer you are going to be looking for with this question is 16.4. Hope this helps you out a little :)
A) 4a+3w
b) 2b+h
c) 3(w+h)
d) (4a+3w)(2b+h) - 3(w+h)
just expand brackets for d and simplify
For 6 hours charges $330
for 9 hours charges x
---------------------------------
x = 9*330/6 = 495 so choice C. is right
Answer:
-6
Step-by-step explanation:
input the numbers
do the problem in the parentheses first
-6-12 = -18
now it becomes
simplify and you'll get
-6
this is because -18 ÷ 3 =
-6
answer
(x+7)^2 + (y-4)^2 = 64
set up equation
the equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where h is the center x coordinate and k is the center y coordinate
values
from the point (-7,4) we know that h = -7 and k = 4
since the radius is 8, r^2 = 8^2 = 64
plug in values
now that we have all the values, we plug them into (x - h)^2 + (y - k)^2 = r^2
(x - h)^2 + (y - k)^2 = r^2
(x - (-7))^2 + (y-4)^2 = 64
(x+7)^2 + (y-4)^2 = 64
