Answer:
Step-by-step explanation:
2x + 1 + x + 23 = 180
3x + 24 = 180
3x = 156
x = 52
2(52) + 1 = 104 + 1 = 105
52 + 23 = 75

Two different solids are shown in figure.
1) A cube of side, 4 cm.
Volume of cube = side * side * side = 4*4*4 = 64 cm cubic centimeters
Surface area of cube = 6 *side * side = 6 *4*4 = 96 cm^2
2) A rectangular prism of dimensions, l =8cm, h= 4 cm and b =2 cm
Volume of rectangular prism = side * side * side =8*4*2 = 64 cm cubic centimeters
Surface area of rectangular prism = 2lb + 2bh + 2hl
= 2*4*8 + 2*8*2 + 2*2*4
= 112 cm^2
The volume of both these solids are same but the surface area is different because volume means holding/containing something while surface area depends on the area of each surface in the figure. The surfaces in the cube are squares but in rectangular prism, the surfaces are rectangles.
Answer:
Step-by-step explanation:
The word "opposite" is indicated by the - sign out front. Mathematically, we multiply a -1 into the parenthesis which, not coincidentally, changes the signs of everything inside the parenthesis, making them "opposite". The opposite of this polynomial is
- a - b - c
the expression represents a quadratic polynomial with 2 terms.The constant term is 1, the leading tern is x and the leading coefficient is 1
