L×W = 13×13
L×W = 169
Remember, the formula of a square is . If I half x, is the new formula. Because the exponent is around the varialbe(x/2), both are squares. Therefore, the formula is .
Therefore, the new area is B: a quarter of the original.
To find the area it’s multiply the base and height: 44*44=1936cm^2
So your answer would be 1936cm^2
I hope this helps :)
answer: the answer is 40.82
step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2
he used the algebra tiles correctly.
given : 3x(2x-1)
since he used algebra tiles .
armando's solution is the same in the solution shown in figure
as he distributed 2x into x and x and wrote them vertically
and also write -1 vertically
and 3x into x and x and x and wrote it horizontally
performing the multiplication in the algebra tiles we get
and solving the given expression :
since solving the expression using tiles and solving the expression algebraically we get the same answer
thus we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
