Using The Almighty Formula (attached)
Note the symbol ^ is used to denote a raise to power
Where from the equation given x^2-5x-7
With a,b,c coefficients
a=1 b=-5 c=-7
From the Almighty Formula
√b^2-4ac=√(-5)^2-4(-7)=√53
Substituting in the Almighty Formula
-(-5) ±√53/2(1)= 5±√53/2
x=5+√53/2 and x=5-√53/2
So the unit rate is 66:1
then you do 66*3=198
198:3
then you do the same thing 66*7=462
462:7
lastly you do 66*15=990
990:15
Answer:
750
Step-by-step explanation:
800 - 8p = 750
(2m + 4) / 8 x 6/m+2
2(m + 2)/8 x 6/ (m+2) : 2 from [2(m] becomes a 1. 6 becomes a 3 , 8 becomes a 4 then cross out 4 and it becomes a 2.
= 3/2
Answer:
You are most likely a right triangle.
Step-by-step explanation: A polygon with 5 sides is the pentagon. A square has 4 angles, so with this, I can already tell that it is a triangle if it has 3 angles, (one less than a square). Then it says that it has 1 right angle. This would make the triangle a right. I hope this helps.
