<u>Question 14</u>
Base angles of an isosceles trapezoid are congruent, so:

The answer to this question is - 3
Answer:
<em>x </em>equals 3.6.
Step-by-step explanation:
A way to solve this equation is to preform the inverse operations on both sides.
1. Add 19 to -19 and 5: 5<em>x </em>+ 6 - 19 + 19 = 5 + 19 ---> 5x + 6 = 24
2. Subtract 6 from 6 and 5: 5x + 6 - 6 = 24 - 6 ---> 5x = 18
3. Divide 5x and 18 by 5: 5x / 5 = 18 / 5 ---> x = 3.6
4. 3.6 is the answer.
To prove it, substitute x with 3.6 in the equation: 5 · 3.6 + 6 - 19 = 5
I hope this made sense and helped you a lot! :)
Area of the bigger rectangle =(18×8)cm
2
=144cm
2
Area of the smaller rectangle =((30−18)×(8−6))=(12×6)cm
2
=72cm
2
∴ Total area = area of smaller rectangle + area of bigger rectangle =(72+144)cm
2
=216cm

Answer:
I'll give you the answers for 1 - 5: 1). 24, 2).19, 3)10, 4)13, 5)-17
Step-by-step explanation:
You simply substitute the corresponding values for the corresponding function:
f(6) if f(x) = 4x so, f(6) = 4(6) = 24
Another example:
f(5) if f(x) = 3x - 2 so, f(5) = 3(5) - 2 = 15 - 2 = 13
