Answer:
2 is the correct information
Step-by-step explanation:
16÷8
2
Answer:
take 1/4 to the other side since 1/2 and 1/4 are like terms then solve for X getting 16/5 as the answer
Have a wonderful time
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>

Answer: 96 m²
Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a 3-dimensional figure.
So to find the surface area of a cube, it's important to understand that each face of a cube has the same area so we can simply find the area of one face of a cube and multiply by the number of faces which is 6.
To find the area of one face of a cube, we can use the formula for the area of a square which is S².
Since the length of a side is 4 meters, we have (4 m)² or 4 meters x 4 meters which is 16 m².
Now, since there are six sides to a cube, we have 6 (16 m)² which is equal to 96 m². So the surface area of the cube is 96 m².
