because if you have two of the same quantity then altogether means add so just add
28=1/2(7)h
Divide by 7 on both sides giving you
4=1/2h
Multiply by 2 on both sides giving you
h=8
Therefore, the height is 8cm.
Answer:
(x - 4)² + (y - 5)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
(x - 4)² + (y - 5)² = 2
with centre (4, 5) and r =
The comparable equation with equivalent left side and r = 2 is
(x - 4)² + (y - 5)² = 4
