The second side of a triangular deck is 4 feet longer than the shortest side, and the third side is 4 feet shorter than twice the length of the shortest side. if the perimeter of the deck is 56 feet, what are the lengths of the three sides?

Let's assume

first side as shortest side

and shortest side =x

we are given

the second side of a triangular deck is 4 feet longer than the shortest side

so, second side is

the third side is 4 feet shorter than twice the length of the shortest side

so, third side is

now, we are given

perimeter =56

so,

first side + second side + third side =56

we get

now, we can solve for x

so,

first side is 14 feet

Second side is:

Third side is:

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
