Gcf is the greatest common factor. THe gcf of 98 and 42 is 14
Answer
Sarah’s graph is a vertical translation of f(x) = x².
Tammy's graph moved 9 units from f(x) = x² in a positive direction.
Sarah's graph has a y-intercept of 9.
Length(width) = area
504 = 14(x)
504/14 = 14(x)/14
x = 504/14
x = 36

hope this helps :D
Here, I'll have a try:
This expression is the multiplication of a binomial and a trinomial.. The binomial has two terms, while the trinomial has three terms. Use the distributive property of multiplication,
Step 1, multiply every term of the trinomial with the first term of the binomial, then multiple every term of the trinomial with the second term of the binomial. Use parenthesis to separate each multiplication to avoid confusion.
step 3, simply every multiplication
step 4, add up like trms
The vertex form of a quadratic function: y = a(x - h)² + k
vertex (h; k)
We have: y = 7(x - 4)² + v
vertex: (4; -2)
therefore: v = -2
