2²-6x-56
this is unfactorable because there is no x on where the number is squared or the -56
Answer:
A
Step-by-step explanation:
5 and 7 are both common factors of 35 and 40
Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.
This leaves A and B. Looking at the equation the difference between the two are the + and -
Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer
Answer:
x = 9
y = -10
Step-by-step explanation:
Answer:
The number is 14
Step-by-step explanation:
Let n be the number. We can set up an equation:
2(n+20)=5n-2
Distribute the left side
2n+40=5n-2
Move like terms to one side. Note that the sign flips when we move a term from one side to the other.
40+2=5n-2n
42=3n
Divide both sides by 3
n=14
Answer:
In an equation y = a(x - h) + k, the axis of symmetry will be x = h. This is because (h, k) is the vertex, and the parabola will be symmetric on both sides of the vertex.
