2.15x-30y-220
3.15x+30y-220
4.15x+30y-64
The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 30(1/2x - 2) + 40(3/4y - 4)
Simplify the expression, then we have
⇒ 30(1/2x - 2) + 40(3/4y - 4)
⇒ 15x - 60 + 30y - 160
⇒ 15x + 30y - 220
The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.

Depending on what is known about triangles ABC and EDC, either the Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), or Hypotenuse-Leg (HL) Postulate might be used to prove their congruence.
In mathematics, there are several postulates that can be used to prove that two triangles are congruent (i.e., identical in shape and size). In the case of triangles ABC and EDC, the appropriate postulate would depend on what information we have about these triangles. If we know that corresponding sides and angles are equal, we could apply the Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), or Hypotenuse-Leg (HL) Postulate. Without specific details about triangles ABC and EDC, I can't determine which postulate would prove their congruence.

Answer:
the answer is 'undefined'
Step-by-step explanation:
Cot is defines as (cos x)/(sin x)
So we can rewrite our expression as...
(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)
or
2(cos 180°)/(sin 180°)
Cos 180° = 1, sin 180° = 0 (you get these from the unit circle)
so we have
2(1/0) = 2/0, which is undefined, because we don't divide by zero
Answer:
8$
Step-by-step explanation:
Not all shapes, a right triangle does not have any parallel sides.
I hope this helped!
