Answer: Rhombus and square</h3>
Explanation:
Any rhombus has its diagonals meet at 90 degree angles. The proof for this is a bit lengthy, so I'll let you handle it. The basic idea is to draw in the diagonals, which forms smaller triangles. Proving those triangles to be congruent leads to supplementary congruent angles, which in turn leads to the 90 degree angles needed.
A square is a special type of rhombus where all four angles are the same (each 90 degrees). Put another way, a square is both a rectangle and a rhombus at the same time.
Some rectangles are not squares, so the non-square rectangles will have the diagonals not be perpendicular.
Answer:
If you take 5 percent of a number and get 60, then what is that number?
In other words, you know that 5 percent of a number is 60 and you want to know what that initial number is.
To solve this problem you multiply 60 by 100 and then divide the total by 5 as follows:
(60 x 100) / 5
When we put that into our calculator, we get the following answer:
1,200
Step-by-step explanation:
Hey there!
Let's plug in our values.
2.5 + (9*7) / 5
Simplify the top:
2.5 + 63 =
65.5
Divide:
65.5 over 5 =
13.1
Therefore, your answer is D.
Hope this helps!

Answer:
The square would be 25p^2 - 90p + 81
Step-by-step explanation:
To get this, use the FOIL method. In this, we multiply the first, outer, inner and last pairings.
First - Multiply the first number in each parenthesis.
5p * 5p = 25p^2
Outer - Multiply the outside numbers in each parenthesis.
5p * -9 = -45p
Inner - Multiply the inner numbers in each parenthesis.
-9 * 5p = -45p
Last = Multiply the last numbers in each parenthesis
-9 * -9 = 81
Now take all of those numbers and add together. Then simplify.
25p^2 - 45p - 45p + 81
25p^2 - 90p + 81
