Answer:
-6125
Step-by-step explanation:
negative 78 squared = -6084
-6084 + 3 - 9 = -6090
-6090 - 5 squared minus 6 minus 4 = --6125
I got confused by "8th" and "a minus" do you mean 3a, and 6a?
Option C:
The perimeter of the rhombus is 100 inches.
Solution:
AC = 30 inches, BD = 40 inches
In rhombus, diagonals bisect each other at right angles.
AE = CE = 15 inches
BE = ED = 20 inches
In ΔAED, ∠E = 90°
Using Pythagorean theorem,





Taking square root on both sides, we get
AD = 25 inches
In rhombus, all sides are equal in length.
AD = DC = CB = BA = 25 inches.
Perimeter = AD + DC + CB + BA
= 25 + 25 + 25 + 25
= 100 inches
The perimeter of the rhombus is 100 inches.
Option C is the correct answer.

Answer:
Step-by-step explanation:
sine = opposite / hypotenuse
- sin y = 7/12
- y = arcsin (7/12)
- y = 35.69
Answer: If the solution's boiling point drops because salt is added to the soltuiton, then the reason the solution boils sooner is the addition of salt to the solution
Step-by-step explanation:
The re are two cause - consequence relations inside an other one.
I use 3 different cause - consequence connectors not to mix them up.
A --> D equals “ D because A “
A --> S equals “ the reason S happens is A “
(A --> D) --> (A --> S) Equals “ if (A --> D) then (A --> S) “
