Answer: 0
Step-by-step explanation:
first you distribute the negative which gives you 7-3-4 which equals 0
Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to
This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.
Combine like terms:
Divide both sides by 12:
We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x = 
°
∠BCD = 3x = 
°
∠CDA = 2x = 
°
∠DAB = 3x = °
Hope this helped!

Step-by-step explanation:
Answer:
{3, 4}
Step-by-step explanation:
"M(x)=(2x-6)(x-4) true statements when M(x)=0 when x= ?" asks us to find the "roots" of M(x); that is, the x values at which M(x) = 0. Thus, we set
(2x - 6)(x - 4) = 0, which is equivalent to 2(x - 3)(x - 4) = 0.
Thus, x - 3 = and x = 3; also x - 4 = 0, so that x = 4.
The roots of M(x) are {3, 4}
Using the language of the original problem: "true statements when M(x)=0 when x=" the correct results, inserted into the blanks, are x = 3 and x = 4.
1.4 you subtract normally it as if you were doing whole numbers
