Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
Answer:
you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S
Step-by-step explanation:
let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.
for walls A= 2*12*8=192
for walls B=2*10*12=160
in total, you need 160+192= 352 square feet of wallpaper
Answer:
90
Step-by-step explanation:
10x - x = 81
9x = 81
x = 9
larger number = 10 x 9 = 90
46 11/32 as the remainder
11 is the remainder and you will put it over the number that you divided by!
I hope this helps. :)
Answer:
218 cm²
Step-by-step explanation:
= high × wide
= 9 × 2
= 18
= 6 × (5+3)
= 6 × 8
= 48
= 8 × (11+5+3)
= 8 × 19
= 152
area throughout
= 152 + 48 + 18
= 218 cm²
