### 2.2+2.2x2

Explanation
The given expression is 2.2 + 2.2x2. To solve this, we need to follow the order of operations, which is multiplication before addition. So, we first multiply 2.2 by 2, which gives us 4.4. Then, we add 2.2 to 4.4, resulting in 6.6. Therefore, the correct answer is 6.6, not 8.8.

### A triangle has sides of 35cm what is its perimeter

Explanation
Since a triangle has three sides, and each side is given as 35cm, we can find the perimeter by adding all three sides together. Therefore, the perimeter of the triangle is 35cm + 35cm + 35cm = 105cm.

### What is 1/2 of 500 multiplied by 6 and then again by 5

Explanation
To find 1/2 of 500, we divide 500 by 2, which gives us 250. Then we multiply 250 by 6, which equals 1500. Finally, we multiply 1500 by 5, resulting in 7500.

### What is a 3-D shape with only one side

Explanation
A sphere is a 3-D shape that has only one side because it is a closed curved surface with no edges or vertices. It is a perfectly symmetrical shape in which every point on the surface is equidistant from the center. Since it has no edges or corners, it can be considered as having only one continuous side.

### Yx4=xy= 1 x=?

Explanation
In the equation yx4 = xy = 1, we are given that yx4 is equal to xy and both are equal to 1. This implies that yx4 and xy are reciprocals of each other. The only number that satisfies this condition is 4, as 4 multiplied by its reciprocal 1/4 equals 1. Therefore, the value of x in this equation is 4.

Rate this question:

• 10.

### X-a=2 a= 6 x=?

Explanation
The equation x - a = 2 is given, and it is stated that a = 6. To find the value of x, we substitute the value of a into the equation, which gives x - 6 = 2. Solving for x, we add 6 to both sides of the equation, resulting in x = 8. Therefore, the value of x is 8.
