Answer:
The length is APPROXIMATELY equal to 12.4.
Step-by-step explanation:
Use the converse of the Pythagorean Theorem (
+
=
[where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:
169-16=153.
≈ 12

Answer:
36x² - 9y²
Step-by-step explanation:
We see that the given expression (6x + 3y)(6x - 3y) looks just like the expression (a + b)(a - b). When multiplied out, this is a difference of squares identity that I highly recommend you memorise:
(a + b)(a - b) = a² - b²
Here, a = 6x and b = 3y, so plug these in:
(6x + 3y)(6x - 3y) = (6x)² - (3y)² = 36x² - 9y²
Using linear pairs,
By the exterior angle theorem,
Answer:
B
Step-by-step explanation:
52.78×6.5%=3.43
52.78×18%=9.50
52.78+3.43+9.50=65.71
