Here is how you solve
4x+12-12=0-12
4x=-12
x=-3
Explanation:
a) The more like a cube or a ball the figure is, the smaller its surface area.
b) Solids with smaller surface area have nearly the same dimension in every direction.
c) Solids with larger surface area have a very high ratio between the largest dimension and the smallest dimension. The flatter or more string-like the figure is, the larger its area.

<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
- 21 x 2/3 = x
- => 7 x 3 x 2/3 = x
- => 7 x 2 = x
- => 14 = x
Hence, <u>the value of x is 14.</u>

Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation

Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
