Answer asap! show all work! will give brainliest! 1) divide using long division ( show all work) (x^2 - 13x - 48) ÷ (x + 3) 2) divide using long division ( show all work) (3x^3 - x^2 - 7x + 6) ÷ (x + 2) 3) using long division determine whether (x + 2) is a factor of x^3 + 3x^2 - 10x - 24 ( show all work)

1) , and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

This means that

2) , and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

This means that

3) will be a factor of if dividing the latter by leaves a remainder of 0.

, and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

and since the remainder is 0, is indeed a factor of .

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
