Answer:
Option C: 
Step-by-step explanation:
Given the side length of a square is 11 units.
Note that 
Since, length cannot be negative, we can eliminate - 11.
Hence, the length of the side of the square is 11 units =
.
Hence, the answer.
Answer:
12
Step-by-step explanation:
21x + 4x = 300 Put brackets around the first two terms.
(21x + 4x) = 300 Pull the x outside the brackets. Use the distributive property. Combine the left
25x = 300 Divide by 25
25x/25=300/25 Do the division
x = 12
maybe since the rhombus is divided into triangles it'll be easier. x = 8
Step-by-step explanation:
the total degrees in a triangle would be 180 and the inner little angles would be 90 degrees so you would solve for (7x - 1) + (4x + 3) + 90 = 180 so 11x + 2 = 90 so 11x = 88 so x = 8
