Answer:
d
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.
Answer:
b. 1:3
Step-by-step explanation:
To find the hypotenuse of the first triangle, use a^2 + b^2 = c^2
c = sqrt (5^2 + 12^2)
c = 13
From here, since they are similar, you can set up a proportion
13:39
1:3
1) 4 divided by 7 = 0.57
2) 4 times 5 = 20 and 4 times 8 = 32
3) 20 plus 32 = 52
4) 0.57 times 52 = 29.64
5) answer : 29.64
i hope this is correct. i tried to break it down.
Answer:
It's the first one.
Step-by-step explanation:
Collect like terms.
x-4+x^2-2x+3
---------------------------
x-7
take x and (-2x): this equals -x
Take (-4) and 3: this equals (-1)
reorder the terms
-x-1+x^2
------------
x-7
Use the commutative property
x^2-x-1
------------
x-7
