Answer: x = 4
Step-by-step explanation:
Distribute the 3 and the 9
[tex]3(x+2)=9(6-x)\\3x+6=54-9x[/tex]
Add 9x to both sides
[tex]12x+6=54[/tex]
Subtract 6 on both sides and simplify
[tex]12x = 48\\x=4[/tex]
Answer:
x=4
Step-by-step explanation:
3 (x+2) = 9 (6-x)
3x + 6 = 54 - 9x
-6 = -6
3x = 48 - 9x
+9x +9x
12x = 48
/12 /12
x = 4
The volume of this cube is 1 ft. What is its surface area? A 6 ft. B 1 ft? C 26 ft? D 10 ft?
Answer:
A
Step-by-step explanation:
The surface area of the cube is 6 ft².
What is a cube?It is a polygon having six faces.
The volume of a cube is side³.
We have,
Volume = 1 ft³
The surface area of the cube = 6a²
Now,
Volume = 1 ft³
This means,
Side = 1 ft
a = 1 ft
So,
The surface area of the cube.
= 6a²
= 6 x 1²
= 6 ft²
Thus,
The surface area of the cube is 6 ft².

Can someone help me with this it's due today
Answer:
37 centimeters
Step-by-step explanation:
First, since the triangles are similar, find out how much larger STR is than HIJ by finding an similar side and dividing the numbers. Since the only similar side that we know both numbers on it ST and HI, so we divide 10 by 4 to get the unit rate, which is 5/2. The missing side on STR is the bottom, so to get it, multiply 6, the bottom of the other triangle, by the unit rate, 5/2, to get the answer of 15. Then, perimeter is all of the sides added up, so 10+12+15=37 cm.

The length of the base of a right triangle with an area of 24 square meters and a height of 4 meters is 12 meters.
The correct option is C.
What is a right-angled triangle?A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.
Given:
An area of the right triangle = 24 square meters.
Height = 4 meters.
Then,
An area of the right triangle = 24 square meters.
1/2 x base x height = 24
1/2 x base x 4 = 24
Base = 12 meters.
Therefore, the base is 12 meters.
