Answer:
x=6
Step-by-step explanation:
x+1
-------
x-6
The expression is undefined when the denominator is zero
x-6 =0
Solving for x
x+6-6 =0+6
x=6
Let x be the total price. And you paid 75% of it which is $135.
x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.
Answer:
E. This polynomial could be factored by using grouping or the perfect squares methods.
Step-by-step explanation:
x^2 + 2x + 1
There is no greatest common factor
This is a perfect square
a^2 + 2ab+ b^2 = ( x+1)^2
We can factor this by grouping
x^2 + 2x + 1
(x^2 +x) + (x+1)
x( x+1) + x+1
Factor out x+1
( x+1) ( x+1)
This is not the difference of squares since there is no subtraction
6.4x + 2.8y = 44.4
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4
-19.2 -19.2
2.8y = 25.2
------ ------
2.8 2.8
y = 9
A=34°
B=76°
C and d = 70°
because a triangle is 180° and we know
a+b+c=180
76+34=110
180-110=70
