Perimeter = a + b + c = 30
Area = 1/2 x a x b = 30
Multiples of 30: 2, 3, 5, 6, 10, 12, 15
For perimeter c = 30- (a+b)
C= sqrt( a^2 + b^2)
Using the possible combinations of the above:
5 and 12:
C = sqrt(5^2 + 12^2) = 13
5 + 12 + 13 = 30 for the perimeter
Area = 1/2 x 5 x 12 = 30
The sides are 5, 12 and 13 cm
The height of this pyramid will be:
√(26^2 - (48/2)^2) = 10cm
So the volume is: V = 1/3 * 48^2 * 10 = 7680 cm^3
Answer:
x = 1.19258 and x = −4.19258
Step-by-step explanation:
The given equation is :

Keep x terms on the left and move the constant to the right side by adding it on both sides.

Take half of the x term and square it.

then add the result to both sides

So,
x = 1.19258 and x = −4.19258
Hence, this is the required solution.
