Answer:
X=70
Step-by-step explanation:
Interior angles of parallel line sum up to be 180° so:
45+(2x-5)=180
45+2x=185
2x=140
x=70
Answer:
B.) 5, -1
Step-by-step explanation:
Formula:
ax^2+bx=c
Shift the equation and set it equal to 0 by subtracting c.
ax^2+bx+c=0
So, in this case:
x^2-4x=5
Shift the equation:
x^2-4x-5=0
a= 1
b= -4
c= -5
Now, to figure out the zeros of an equation like this:
You need to find two numbers that multiply to c (-5), but also add to b (-4).
These numbers are 5 and -1
So, the zeros of the equation are 5 and -1.

Answer:
6x^2-7x-20 (c)
Step-by-step explanation:
(3x+4)(2x−5)
=(3x+4)(2x+−5)
=(3x)(2x)+(3x)(−5)+(4)(2x)+(4)(−5)
=6x^2−15x+8x−20
=6x^2-7x-20
