Answer:
If you take 32 percent of a number and get 64, then what is that number? In other words, you know that 32 percent of a number is 64 and you want to know what that initial number is. Therefore, the answer to "64 is 32 percent of what number?" is 200, and you can also derive that 32 percent of 200 equals 64.
Step-by-step explanation:
Answer:
Value of b is all the numbers.
All the numbers will satisfy the value of b.
Step-by-step explanation:
4b + 21 = b + 3 ( b + 7 )
4b + 21 = b + 3b + 21
4b + 21 = 4b + 21
We want to make x^2-3x into a perfect square trinomial. An example of such a trinomial is x^2 + 6x + 9, which is equivalent to the square of (x+3).
From x^2-3x we see that the coefficient of x is -3. Divide this coefficient, -3, by 2, obtaining -3/2. Now square this result: square -3/2. Result: 9/4.
Adding 9/4 to x^2-3x makes x^2-3x into a perfect square trinomial.
Answer:
False
Step-by-step explanation:
2
= x - 8
Add 8 to each side
2+8 = x-8+8
10 = x
x=4 is not a solution
