So hmm notice the picture below
running a segment from the right-angle perpendicular to the opposite side, gives three similar triangles, one small, a medium and a large one
now, using proportions, you can simply

and solve for "x"
150+(.10)x+x=200
.10x+x=50
1.10x=50
x=45.45454545
Answer:
The square of a monomial is 
Step-by-step explanation:
Consider the provided monomial.

We need to Write the expression as a square of a monomial.
The above expression can be written as:



Hence, the square of a monomial is 
65
1. you work in the parentheses and multiply 2.8 by 5 which is 14
2. you divide 14 by 7 which is 2
3. you follow PEMDAS and multiply 26 by what is in the parentheses (2) which is 52
4. you add 13 with 52 which is 65
hope this helped!!
