Answer: B. YesStep-by-step explanation:We have been given that in parallelogram ABCD, D is a right angle. We are asked to determine whether the given parallelogram is rectangle or not.Let us recall parallelogram properties.Opposite angles of parallelogram are equal.Consecutive angles of parallelogram are supplementary.Since D is a right angle, so its opposite angle will be right angle as well and consecutive angles of angle D will be right angles as well.Therefore, the parallelogram ABCD is a rectangle and option B is the correct choice.

Answer:
{x,y} = {67/16,-15/4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -8x + 26
[2] y = -4x + 13
// Plug this in for variable y in equation [1]
[1] 4x + 5•(-4x+13) = -2
[1] -16x = -67
// Solve equation [1] for the variable x
[1] 16x = 67
[1] x = 67/16
// By now we know this much :
x = 67/16
y = -4x+13
// Use the x value to solve for y
y = -4(67/16)+13 = -15/4
The answer is 45
Solution:
Given expression is 4x + 5 + 2x + y.
To find the value of this expression when x = 6 and y = 4.
Substitute x = 6 and y = 4 in the given expression.
4x + 5 + 2x + y = 4(6) + 5 + 2(6) + 4
= 24 + 5 + 12 + 4
= 45
4x + 5 + 2x + y = 45
Hence, the value of 4x + 5 + 2x + y if x = 6 and y = 4 is 45.
The correct answer is 64/6.
