Since it is a rectangular prism, the front and back are the same. the sides are the same and the top and bottom are the same. You would find the area of the front and back first. Since they both have the same measurements, you can find the area of one of the faces and multiply by 2.
A=BH
A= 3x5
A=15
15x2=30
So the front and back's area is 30. Now you find the area of both sides. They are both rectangle so the formula is A=BH.
A=BH
A=3x5
A=15
15x2=30
Now you find the area of the top and bottom. It is also a rectangle so you will use the same formula.
A=BH
A=3x3
A=9
9x2=18
Finally, you add all these measurements together adn that is the surface area.
This surface area of this rectangle prism is 78.
No it doesn't be i thought that it you would have to find a domain but i couldn't
Answer:
18
Step-by-step explanation:
the factors and prime factorization of 36 and 54. The biggest common factor number is the GCF number. So the greatest common factor 36 and 54 is 18.
Answer:
Option 1
Step-by-step explanation:
You must multiply (2x + 3) by (x + 4). I use the FOIL method.
(2x + 3)(x + 4)
Multiply
2x² + 8x +3x + 12
Simplify
2x² + 11x + 12
To check the answer, you could factor this trinomial back into a pair of binomials.
