M(x) = 5x + 4 n(x) = 6x - 9
Part 1 (m + n)(x) = 5x + 4 + 6x - 9
= 11x - 5
Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36
Part 3 m[n(x)] = 5(6x - 9) + 4
= 30x - 45 + 4
= 30x - 41

Answer:
120
Step-by-step explanation:
The sum of the angles in a quadrilateral is 360 degrees
2t+t+2t+t = 360
6t = 360
Divide by 6
6t/6 = 360/6
t = 60
Angle Z = 2t
Angle Z = 2*60 = 120

Step-by-step explanation:
Answer:
<u>The correct answer is x = 5 2/3 - 7 2y/3</u>
Step-by-step explanation:
1. Let's solve the equation for x
3x + 23y = 17
3x = 17 - 23y (Subtracting 23y at both sides)
3x/3 = 17/3 - 23y/3 (Dividing by 3 at both sides)
x = 17/3 - 23y/3
2. Proof of 17/3 - 23y/3 as the value of x
3x + 23y = 17
3(17/3 - 23y/3) + 23y = 17 (Multiplying the values inside the parenthesis)
17 - 23y + 23y = 17
<u>17 = 17</u>
<u>It has been proved that x = 17/3 - 23y/3</u>
<u>3. </u>However we can simplify
17/3 - 23y/3
<u>5 2/3 - 7 2y/3</u>
<u>There isn't a system of equations that will allow us to find y</u>
