Answer: 7 is 1/8, 8 is 2/8 or 1/4
Step-by-step explanation:
9 because 9x3=27 or 27/3=9
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Answer:
x = 9
Step-by-step explanation:
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
5(x - 6 + 5) = 4(x - 3 + 4)
5(x - 1) = 4(x + 1) ← distribute parenthesis on both sides
5x - 5 = 4x + 4 ( subtract 4x from both sides )
x - 5 = 4 ( add 5 to both sides )
x = 9
