Answer:
64
Step-by-step explanation:
its subtracting the square of the numbers
169-7²= 120
120-6²=84
84-5²=59
59-4²=43
43-3²=34
34-2²=30
so the sum is 64
An equation of a parabola is usually in the form f(x)=ax^2+bx+c, so look for equations in this format.
Answer: Choice A) Add 3.8 to both sides of the equation
Explanation:
If we knew the value of w, then we would replace it and apply PEMDAS.
However, we don't know the value of w, so we undo each step of PEMDAS going backwards.
We start with the "S" of PEMDAS, and undo the subtraction. To undo subtraction, you apply addition. To undo that "minus 3.8" we add 3.8 to both sides.
