(multiply)
= 12+[tex]3x^{2}[/tex]-9x+7
(calculate)
=19+[tex]3x^{2}[/tex]-9x
(reorder the terms)
= 19+[tex]3x^{2}[/tex]-9x

The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?
*see attachment for the diagram of the triangular prism box
Answer:
528.8 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
Area of triangular base (BA) = ½*b*h
b = 24.5 in.
h = 12 in.
BA = ½*24.5*12 = 147 in.²
Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.
Height of prism = 4 in.
Plug in the values into the surface area formula:
Surface area of prism = 2(147) + 58.7*4
= 294 + 234.8
= 528.8 in.²

A wedding reception was
being held at Stefano's
restaurant. They charged
$2.00 per person for
appetizers, $20.00 per
person for the main course
and $250 for the wedding
cake. There were 50 people
at the reception. What was
the total cost of the
reception?
Answer:
the total cost of the wedding would be: 1,350
Step-by-step explanation:
2×50=100 and 20×50=1,000
100+1,000=1,100
1,100+ 250= 1,350
total for wedding is 1,350
:)
Answer: The answer for this problem is $1350.
Step-by-step explanation:
The first thing you do is to see how much money for the appetizers and the main course did all 50 people pay.
50 x 2 = 100, how much money in total for the appetizers
50 x 20 = 1000, how much money in total for the main course
Once you're done with that! Next, you add the total prices for the appetizers and the wedding cake. Then, you add up the $250, so you get your answer!
$100 + $1000 = $1100
$1100 + $250 = $1350
This is how you get the answer!

A pyramid and a cone are both 10 centimeters tall and have the same
volume. What statement must be true about the two solids?
A. The vertical cross-sections of the pyramid and cone at the same
width must have the same area,
B. The area of the cross-sections of the pyramid and cone are
multiples of each other,
C. The horizontal cross-sections of the pyramid and cone at the
same height must have the same area
D. The cross-sections of the pyramid and cone are the same shape
9514 1404 393
Answer:
C. The horizontal cross-sections of the pyramid and cone at the same height must have the same area
Step-by-step explanation:
Cavalieri's principle says that solids with corresponding cross sections of the same area will have the same volume. Statement C is the converse of this principle.

Answer:
16 feet
Step-by-step explanation:
We are Given that
We have a 34 foot ladder leaning against a 30 foot buildingWe are asked to find the distance of the bottom ladder from bottom of the building.A ladder leaning against a object makes the ladder slanted so that means 34 is our hypotense.
The building height And distance of the bottom of ladder and building is our legs so our formula we use is
[tex] {30}^{2} + {x}^{2} = {34}^{2} [/tex]
[tex]900 + {x}^{2} = 1156[/tex]
[tex] {x}^{2} = 256[/tex]

what is T/8 = -4 solve for T
Answer:
The answer is -32
Step-by-step explanation:
Multiply both sides by 8 to cancel 8 as the denominator and you have T = -32
How do I solve this?
I have the answer but what is the step-by-step explanation.
-7 = 1 + 2/3n
Subtract 1 from both sides:
-8 = 2/3n
Multiply both sides by 3:
-24 = 2n
Divide both sides by 2:
N= -12
Answer:
n=-12
Step-by-step explanation:
Okay this isn't to hard first in the equation you must subtract 1 from both sides
So this: -7=1+2/3n
Becomes This: -8=2/3n
Then I divided by 2 on both sides to get:-4=1/3n
Then I multiplied by three to get -12=n
