2(5*10)+2(10*4)+2(5*4)=
2(50)+2(40)+2(20)=100+80+40=
220 cm^2
I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.
The Answer is:
(5a2-3a+8)+(-4a2-1)+(15a+11)
Answer:
Step-by-step explanation:
One-fourth x + 2 = 
Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4
Bringing terms with x to the left Hand Side i.e. collecting like terms
On Cross multiplying
7x = -7 X 8
x=-8
Answer:
A) 2(9x - 2)
Step-by-step explanation:
The greatest common factor of 18x and -4 is 2.
B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.
C is wrong because 18x cannot be divided by 4 to produce a whole number.
D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.
The volume of the pyramid is 432ft3.
