Type the correct answer in each box.
solve the quadratic equation. write your solutions in the blanks, starting with the smaller value.

4x2– 7 = 9

x = ±2 (x = 2 or -2)

Start with the equation .

Add 7 on both sides of the equation to get .

Divide both sides by 4 to get .

Now, find the square root of each side to get a final answer of , which means x can be either 2 or -2.

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

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
