Answer:
4
Step-by-step explanation:
Hi, these equations are pretty easy actually, first thing you should know when working with variables is that you always want to leave the variable alone, let's take the third excersise for example, 12x + 2 = 146. Here you just do the opposite on the other side of the equation depending if the number is positive or negative. Since x is being multiplied by 12 you first get rid of the 2, since its positive you subtract it to 146. Now the answer should be 12x = 144. Now since you're multiplying 12 to x you just divide 12 from 144, 144/12 = 12
x = 12
You just divide 79 into 4,032. Have you learned long division yet?
a) Cube area = 6a^2
a = 6(5.25)^2
5.25 * 5.25 = 27.5625 * 6 = 165.375
Rounded, thats 165.38
b) Rectangular prism area = 2(wl + hl + hw)
Lets say l = 6.8, w = 8.2, h = 10
It equals about 441.52
A new shape with an area of 1 square unit that is not a square can be formed by combining two small triangles
<h3>How to determine the new shape?</h3>
The given parameters are:
- Area of square = 1 square unit
- Large triangles = 2
- Medium triangles = 1
- Small triangles = 4
The area of each small triangle is:
Area = 0.5 square unit
Multiply both sides by 2
2 * Area of triangle = 1 square unit
Substitute Area of square = 1 square unit
2 * Area of triangle = Area of square
This means that a new shape can be formed by combining two small triangles
