Is the box cube or a parallelogram?
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
Let us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ =
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ =
∴ y = -2
∴ The values of x and y are x = -3 and y = -2

Answer: 123.5 in^2
Step-by-step explanation: The formula for the area of a trapezoid is a+b/2 x h. In other words, base 1 plus base 2 divided by 2, and multiplied by the height. Plug in the numbers. The equation is:
6+7/2 x 19 = 123.5.
Since you are finding the area, the answer would be in inches squared. The answer is 123.5 in^2.
