Answer:
Step-by-step explanation:
Answer:46.28, 193.75
The first one you add (((2.5+4.7)x3.05)+1.18)x2. And the second one you (7.50+0.25)x25.
(x+1)² + y² = 36
<u>Equation of a circle:</u>
(x-h)² + (y-k)² = r²
Center: (h,k)
Radius: r
Given a center of (-1,0) and a radius of 6, we have for our equation:
(x-(-1))² + (y-0)² = 6²
ax - b = c
add b to each side
ax-b +b = c+b
ax = c+b
divide by a
ax/a = (c+b)/a
x = (c+b)/a
£160
£262 x (100% - 39%) = £159.82 ≈ £160
