Answer:
The trinomial is not a perfect square trinomial because the third term is not a square.
Step-by-step explanation:
A trinomial is an expression composed of three terms that are joined together by addition or subtraction.
A perfect square is created when a value is multiplied times itself. Thus, , making the trinomial a² + 2ab + b² a perfect square.
To show that a trinomial is a perfect square you must show that if the first and third terms are squares, figure out what they're squares of. Multiply those things, multiply that product by 2, and then compare your result with the original quadratic's middle term. If you've got a match (ignoring the sign), then you've got a perfect-square trinomial.
The trinomial is not a perfect square trinomial because the third term is not a square.
Answer:
91.204 cubic feet
Step-by-step explanation:
We are given that
Height of great pyramid, h=480feet
Side of square base, a=755 feet
Height of Danny's pyramid, h'=480/100 feet
Side of square base of Danny's pyramid, a'=755/100 feet
We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.
We know that
Volume of square base pyramid, V=
Where a= Side of base
h=Height of pyramid
Using the formula
Volume of Danny's pyramid=
Volume of Danny's pyramid=91.204 cubic feet
