The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
Answer: The acute angle between diagonals is 50
Step-by-step explanation:
Red angle = 50 because An exterior angle of a triangle is equal to the sum of the opposite interior angles (pink angles).
Alternatively:
Green angle is 130 by sum of interior angles of a triangle.
Red angle is 50 by Adjacent angles
Answer:
The factored equation would be 4x(3y + 7z)
Step-by-step explanation:
In order to find this, look for the greatest common factor and pull it out. Since both have factors of 4 and both have an x, we pull those out. We then divide each term by 4x to get what is left over.
The surface area of the cone will be : 169.65 so it would be answer A as 54 x pi = 169.646003
Answer:
x = 41/3
y = 199/3
Step-by-step explanation:
Solve using system of equations
x is smaller number, y is larger
eq1> y + 2 = 5x > y = 5x - 2
eq2> 80 = x + y > y = 80 - x
equate
80 - x = 5x - 2
Solving:
x = 41/3
y = 199/3
