Answer:
Step-by-step explanation:
2x + 4x + 180
We have to do combine like terms.
2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.
All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.

Answer:
24.5 inches
Step-by-step explanation:
The ratio of the length of the toucan’s bill to the length of its body can be expressed as
(1: 3.5)
Then if the bill is 7 inches, then the Length of the body will be X
1: 3.5
7: X
If we cross multiply, we have
X= 7×3.5
X= 24.5
Hence, the Length of the body is 24.5 inches
Answer: Yes they are right triangles
Explanation:
The square grid markers help us line up the angles to see that angle OBC is a 90 degree angle, and so is angle OB'C'. Any time a vertical and horizontal line meet up is when you have a 90 degree angle. A right triangle is one where it has a 90 degree angle (aka a right angle).
Extra info: it can be shown that triangle OBC is similar to triangle OB'C', which leads to the fact that the triangles are proportional.
