1.
Part A.
bh + hr = 25
h( b + r ) = 25
h = 25/ b + r
Part B
hr = 25 - bh
r = (25 - bh)/h
r = 25/h - b
2.
Part A.
xy = r - h
-h = -r + xy
divide both sides by -1
h = r - xy
Part B
xy = r - h
xy + h = r
r = xy + h
3.
4x - 2y = 8
-2y = 8 - 4x
divide through by -2
y = 8/-2- 4x/-2
y = -4 + 2x
therefore Camille solved the equation correctly

Answer:
11x -2
Step-by-step explanation:
you add like terms so this will be the answer.
Answer:
283 cm²
Step-by-step explanation:
To find the surface area of the cone, we don't need the height since we already have the slant height.
The surface area of a cone is given as:
A = (π * r²) + (π * r * L)
Where r = radius of base of cone
L = slant height of cone
From the question, r = 5 cm and L = 13 cm
Hence:
A = (π * 5²) + (π * 5 * 13)
A = 78.55 + 204.23
A = 282.78 cm² = 283 cm² (approximating to the nearest whole number)
The approximate surface area of the cone is 283 cm²
(3x - 8)(2x - 2)
(6x² - 6x - 16x + 16)
6x² - 22x + 16
