There are 3 sides and 3 angles per shape, because they are both triangles. hope this helped you out!!!
Answer:
No solutions
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
The answer here is C. Let's proof.
Since we are dealing with whole numbers, select a constant for x to satisfy that y will result a whole number.
If x = 1, then the function would be 1 + 4y = 9. Solving for y,
4y = 9 - 1
4y = 8
y = 2
In ordered pair, that is (1,2)
Next, if x = 5, then 5 + 4y = 9. Solving for y,
4y = 9 - 5
4y = 4
y = 1
In ordered pair, that is (5,1).
Lastly, if x = 9, then 9 + 4y = 9. Solving for y,
4y = 9 - 9
y = 0/4
y = 0
In order pair, that is (9,0).

Answer:
-2x^2 +8x-10
Step-by-step explanation:
(x^2+3x−7)−(3x^2−5x+3)
Distribute the minus sign
(x^2+3x−7)−3x^2+5x-3
I like to line them up vertically
x^2 +3x−7
−3x^2+5x-3
-------------------
-2x^2 +8x-10
