The answer is B, rad 2 over 2
Answer:
sum of twice a number and three is 21
2x + 3 = 21
x = 9
Surface area is the sum of the areas of each side of a three dimensional object.
There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.
So the surface area is:
2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2
Answer:
3z(2x - 3)
Step-by-step explanation:
Area of a rectangle, a = height * width
height, h = 3z
width, w = 2x - 3
a = 3z * (2x -3)
expand
a = 6xz - 9z
a = 3z(2x - 3)
Answer:
Step-by-step explanation:
PRQ is the right angle. It is the angle opposite a diameter which is 90 degrees.
PQR is an acute angle. I can make no other statement about it without one more piece of information.
