Answer:
x=1
Step-by-step explanation:
-2x + 4 = 5 - 3x
Add 3x to each side
-2x+3x + 4 = 5 - 3x+3x
x +4 =5
Subtract 4 from each side
x+4-4 =5-4
x =1
Answer:
Explanation:
You just need to find the ratio of lengths of one of the sides and apply it to the unknown side:
72
24
=
3
This means that the triangle on the right has sides that are 3 times the length of the smaller triangle.

total of interior angles for a 6 sided polygon = 720
150 + 152 + 91 +90+90 = 573
x = 720 - 573
x = 147
Answer:
-2 is a zero of the polynomial. 2 is not a zero of the polynomial.
Step-by-step explanation:
A value of x is a zero of a polynomial if when it is substituted for x in the polynomial, it makes the polynomial evaluate to zero.
The polynomial is x + 2
Let x = -2:
x + 2 = -2 + 2 = 0
-2 is a zero of the polynomial.
Let x = 2:
x + 2 = 2 + 2 = 4
2 is not a zero of the polynomial.
