Answer:
Width = 110 ft
Step-by-step explanation:
width = x
length = x + 300
To find the width, we use the formula for perimeter, substituting 1040 for perimeter, x + 300 for length, and x for width:
![P=2(l+w)\\\\1040=2[(x+300)+x]](https://tex.z-dn.net/?f=P%3D2%28l%2Bw%29%5C%5C%5C%5C1040%3D2%5B%28x%2B300%29%2Bx%5D)
Combine like terms inside the brackets:
Distribute the 2 within the parentheses:
Subtract 600 from both sides:
Divide both sides by 4:
Therefore, the width is 110 ft and the length is 410 ft. To verify, we can check that the perimeter equals 1,040 ft.
Answer:
256 sq cm
Step-by-step explanation:
cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.
The cross-section described is shown below.
The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.
A=lw
=(16cm) (16cm)
=256 sq cm
So, the area of the cross-section is 256 sq cm.

Answer:
M(9;5), I think so. M is midpoint of AB so separate 2
Answer:
2 1/4
Step-by-step explanation:
Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.
To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
