Answer:
Well, you didn't show the equation . However we can generate an equation
by multiplying (x - 2.5) * (x +3)
x^2 -2.5x +3x -7.5 = 0
x^2 +.5x -7.5 = 0
DOUBLE-CHECK
Solving with the quadratic formula:
x = 2.5 and x = -3
CORRECT!!!
Step-by-step explanation:
Hey! What you can do is plug them in or solve for x.
This is how you solve for x:
since its x is divided by -4 and you want to get x alone you should multiply -4 to the other side and so it would be x = -4*8.
That is -32.
The answer is A!
Hope this helps!
You would do: 9+18+20=47-10=37
So your answer is 37
Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
