Answer:
Ok so the area of the frame is 18*12 = 216cm^2
Let’s suppose the width of the frame is x
The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432
4x^2 + 60x + 216 = 432
4x^2 + 60x - 216 = 0
x^2 + 15x - 54 = 0
(x+18)(x-3) = 0
Therefore x = {-18,3}
Since width of the frame has to be positive, the width has to be 3cm Step-
i hope i helped!
Answer:
x = 18
Step-by-step explanation:
Given two intersecting chords inside a circle, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
7x = 21 × 6 = 126 ( divide both sides by 7 )
x = 18
For this case we have that the area of the kite is given by the area of two triangles, the triangles share the same base of 3 + 3 = 6 meters and one has height of 2m and the other height of 4m.
So, the total area is given by:
Thus, the area of the kite is

Answer:
7/24
Step-by-step explanation:
Let
x-----> the shaded area
we know that
x+\frac{1}{3}+\frac{3}{8}=1
Because the complete circle represent the 100\%
and
