Let's not look at the option and try to solve it.
√x=7
Let's look at this. Square roots are the number that is multiplied by itself to make that number. For example, 2 is the square root of 4, 3 is the square root of 9.
We need to multiply 7 by itself to find x.
7×7=49
So, D. =49.
Answer:
$11 Dollar
Step-by-step explanation:
35 - 24 = 11

Answer:
49
Step-by-step explanation:
Because there is a minus sign infront of x-3, we can convert x-3 into the negative form:
- * x
- * -3
-x + 3
Which gives us:
(-x + 3)(x + 11)
Now expand the brackets with the formula:
(a + b)(c + d) = ac + ad + bc + bd
-x * x = -x²
-x * 11 = -11x
3 * x = 3x
3 * 11 = 33
-x² - 11x + 3x + 33
-x² - 8x + 33
The formula for finding the x coordinate of a vertex in a quadratic equation is:
x = 
Plug known variables in:



Now, to find the y coordinate, plug this variable back into the quadratic equation:
-x² - 8x + 33

y = 49
So the y coordinate of the vertex is 49.
