Remember what we know about vertical angles and solve for x.
Answer:
9514 1404 393
Answer:
(b) √55
Step-by-step explanation:
The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:
y/5 = 11/y
y² = 55 . . . . . . multiply by 5y
y = √55 . . . . . take the square root
__
And x=4√5 by looking at ratios of short side to hypotenuse.
3x + 4 - 5 (x + 2) is an equation ; -6 = 2x
Given,
3x + 4 - 5 (x + 2)
We have to find this is whether an expression, equation or inequality.
First we have to solve this:
3x + 4 - 5 (x + 2)
3x + 4 - 5x - 10
- 2x - 6
-6 = 2x
Here, we can identify this is an equation.
What is an equation?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
