The formula for area of a trapezoid is 1/2 h (base1+base2) so, if you input the information, it becomes 1/2 14(19+23) simplified once: 7(42) final answer: 294cm².
Answer:
x = -10
Step-by-step explanation:
move all the constants (numbers without variables) to one side to get
-4x = 42 - 2
-4x = 40
multiply by -1
4x = -40
divide by 4
x = -10
