Answer:
-3 + 4sqrt(2)
-3 - 4sqrt(2)
Step-by-step explanation:
(x – 4)(x + 10) = -17
FOIL on the left hand side (First outer inner last)
x^2 +10x-4x-40 = -17
x^2 +6x-40 =-17
Add 17 to each side
x^2 +6x-40+17 =-17+17
x^2 +6x -23 = 0
Using the quadratic formula
-b + - sqrt(b^2 -4ac)
-------------------------------
2a
where ax^2 +bx+c=0
-6 + - sqrt(6^2 -4*1*-23)
-------------------------------
2*1
-6 + - sqrt(36 +92)
-------------------------------
2
-6 + - sqrt(128)
-------------------------------
2
-6 + - 8sqrt(2)
-------------------------------
2
Divide top and bottom by 2
-3 + - 4sqrt(2)
Okay, so first of all, if the trapezoid was translated right 4,
Then all the (x)'s should be 4 more than the original value
For example: (2,-3) <span>→ (6,-3)
Now since the Trapezoid was translated down 3,
Then all the (y)'s should be 3 less than the original value
For example: (2,-3) </span><span>→ (2,-6)
Now do this to all the Vertices
</span>
Final Answer: <span>
Option 2</span>
Answer:
King size(x): 3
Regular size(y): 2
Steps:
System of Equations:
x+y = 5
3.75x+1.75y = 14.75
Multiply 3.75 on all sides.
3.75x+3.75y = 18.75
3.75x+1.75y = 14.75
Subtract top and bottom
2y = 4
/2 /2
y = 2
After you know regular size amount, figure out king size ----3.
5-2 = 3.
Answer:
the bottom is 12 top is 6 middle is 4
It is option 1 because that is the only one that makes sense
