Answer
$36
Step-by-step explanation:
You multiply 0.8 by 20 since 0.8 is also 80% and you get 16. Since you want 80% more than 20 you add together to get $36. Hope it helped!
Step-by-step explanation:
Find the Center and Radius (x-4)^2+y^2=4

Match the values in this circle to those of the standard form. The variable
r
represents the radius of the circle,
h
represents the x-offset from the origin, and
k
represents the y-offset from origin.
r
=
2
h
=
4
k
=

The center of the circle is found at

Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>Find its value when x = 4 and y = 1, substitute:</u>
- 3(4 + 1) + 2*4² + (1 + 1)² =
- 3*5 + 2*16 + 2² =
- 15 + 32 + 4 =
- 51
Perimeter = (x+2) + x + (x+2) + x
Perimeter = 4x + 4
Area = x(x+2)
Area = x^2 + 2x
Yes because they both have the same degrees, but one is slightly rotated
