Answer:
Step-by-step explanation:
I assume that you need simplification of the given expression.
The given expression is:
Using distributive property and multiplying 2 inside the parenthesis and 1 inside the other parenthesis. This gives,
Therefore, is equal to:
Now, combining like terms using the commutative property of addition, we get:
Therefore, the simplified form is 
Answer:
B
Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
The value of k is the amount by which the function f(x) is translated upward to give the function g(x). We can compare y-intercepts to see that the y-intercept of g(x) is 5 -2 = 3 units more than the y-intercept of f(x). This means ...
g(x) = f(x) +3
Comparing to ...
g(x) = f(x) +k
we see that k = 3.
Answer:
(x−5y)(9x+8)
Step-by-step explanation:
9x^2−45yx+8x−40y
Do the grouping 9x^2−45yx+8x−40y=(9x^2−45yx)+(8x−40y), and factor out 9x in the first and 8 in the second group.
9x(x−5y)+8(x−5y)
Factor out common term x−5y by using distributive property.
(x−5y)(9x+8)
Answer:
x=0.5
