Answer:
My brain just exploded. I tried imagining what the shape would look like, and that didn't work. Also, I tried drawing the shape and that didn't work. I have no idea what the shape looks like. If you still need help with this question, maybe you can repost it with an image attached so we can know what the shape looks like.
A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
Given:
LMN is an equilateral triangle.
LM = LN = MN = 12 cm
To find:
The height of the triangle h.
Solution:
In a right angle triangle,
Multiply both sides by 12.
Therefore, the height of the triangle is 
cm.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
Point (7, 0)
Equation y = x - 7
<u>Step 2: Find</u>
- Substitute in point [Equation]: 0 = 7 - 7
- Subtract: 0 = 0
Since 0 = 0 is true, then it would be a solution to the equation.
Answer:
The number is 8.
Step-by-step explanation:
Write an equation then solve by isolating the variable.
let x be the number
4x + 15 = 47 Subtract 15 from both sides
4x = 47 - 15
4x = 32 Divide both sides by 4
x = 32/4
x = 8
Therefore the number is 8.
