40x-72 because 8×5x is 40x and 8×9 is 72
The Lateral area of the cube = 900 in.²
The Surface area of the cube = 1,350 in.².
<h3>What is the Lateral Area of a Cube?</h3>
A cube's lateral area is the area covered by the lateral surfaces of the cube shape. The formula for the lateral area of a cube is given as: LA = 4a², where:
a = edge length of cube.
<h3>What is the Surface Area of a Cube?</h3>
The surface area of a cube is the total area of all its 6 surfaces. The formula for finding the surface area of a cube is: 6a², where:
a = edge length of cube.
Edge length of cube (a) = 15 in.
Lateral area = 4a² = 4(15²)
Lateral area = 4(225)
Lateral area of the cube = 900 in.²
Surface area = 6a² = 6(15²)
Surface area = 6(225)
Surface area of the cube = 1,350 in.².

Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
x = 9
