a perfect square trinomial, (x + y)² = x² + 2xy + y²
so, if we have the x of the bx, what is left is the b
the expression would have to be (x + 7)², since we have the 49 and the x²
so, what's left: x² + 14x + 49,
b = 14

Answer:
14
Step-by-step explanation:
I first multiplied 490 by 3/7
giving me 1470/7
I divide 1470 by 7 giving me 210
As I got 210
I multiplied 210 with 2 and got 410/3
I divided 410 by 3, getting 140.
It then said half of what was delivered was put into 5 pound bags, so
140× 1/2 or 140÷2 is 70
70 divided by 5 is 14
They made 14 5-pound bags.
Answer:
<h2>D. g(x) = (x - 4)²</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
=========================================
The graph of f(x) shifted by 4 units to the right. Therefore, the equation g(x) is:
g(x) = f(x - 4) = (x -4)²
Answer:
d=-18
a=51
x=-4
c=13/3
Step-by-step explanation:
1. subtract 6 from both sides
divide both sides by -2
2. add 2 to both sides
times both sides by 3
3. times both sides by 4
divide both sides by 9
4. multiply the 10 out into the parenthesis add the 10c and 2c to get 12 c
add 40 to both sides
divide both sides by 3
