9-8x^2+2x^4 is this a trinomial​
Svetradugi [14.3K]

Yes. A monomial is a term composed by a coefficient and powers of variables multiplied with each other, for example

3xy^3z^2

is a monomial.

In your case, the monomials are

9,\quad 8x^2,\quad 2x^4

As the name suggests, a trinomial is the sum of three monomials, which is exactly your case.

Which shows the dimensions of two rectangular prisms that have volumes of 72 cm3 but different surface areas? A. 6 cm by 3 cm by
Nookie1986 [14]
To solve, lets find the volumes of all of the options...

V=l*w*h

A. 
6*3*4=72cm³
12*2*3=72cm³

B.
2*4*9=72cm³
9*4*2=72cm³

C.
3*3*8=72cm³
2*6*8=96cm³

D.
6*3*4=72cm³
9*4*3=108cm³

We can conclude that C & D aren't the answer, since they contain prisms that don't have a volume of 72cm³.

Now lets solve for the surface area of A and B...

A. 
sA=2(wh+lw+lh)=2(6*3+4*6+4*3)=2(18+24+12)=2(54)=108cm²
sA=2(wh+lw+lh)=2(12*2+3*12+3*2)=2(24+36+6)=2(56)=112cm²


B.
sA=2(wh+lw+lh)=2(2*4+9*2+9*4)=2(8+18+36)=2(62)=124cm²
sA=2(wh+lw+lh)=2(9*4+2*9+2*4)=2(36+18+8)=2(62)=124cm²

A is the only option with both similar volumes of 72cm³ and different surface areas...

I NEED HELP PLEASEEE
Gwar [14]

Answer:

b = \sqrt{333}

Step-by-step explanation:

1. We can use the Pythagorean Theorem to find the missing side, b.

  • 14^2 + b^2 = 23^2

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (14*14)+b^2 =(23*23)
  • 196 + b^2 = 529

Step 2: Subtract 196 from both sides.

  • 196 + b^2 - 196 = 529 - 196
  • b^2 = 333

Step 3: Take square root of both sides.

  • \sqrt{b^2} = \sqrt{333}
  • b = \sqrt{333}

Step 4: Check if solution is correct.

  • 14^2 + \sqrt{333^2} = 23^2
  • (14*14)+(\sqrt{333} *\sqrt{333})=23*23
  • 196 + 333 = 529
  • 529 = 529

Therefore, b = \sqrt{333}.
