Answer:
LHS = RHS
Step-by-step explanation:
Given: 0.6 + (-1) - (- 0. 8) - 0. 4 = 0
RHS = 0
We will compute LHS now.
We can re write the question as follows:
= 0. 6 - 1 + 0. 8 - 0. 4
We use BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction) to solve further.
So, we add the terms first.
= 0. 6 + 0. 8 - 1 - 0. 4
= 1 . 4 - (1 + 0. 4)
= 1. 4 - 1 . 4
= 0
∴ LHS = 0
This matches with the given question.
LHS = RHS
I think I got it. Correct me if I am wrong.
Parallelogram diagram I believe down below. We must find the height and then the area using Pythagorean theorem. Since the green shaded part is a 30-60-90 triangle, the base is 1/2 the hypotenuse, therefore it is 3. Now we calculate the height with it.
A^2 + B^2 = C^2
A^2 + 3^2 = 6^2
A^2 + 9 = 36
A^2 = 27
A = 3√3
Therefore the height is 3√3
Now calculate the area using A = bh
A = bh
= (12)(3√3)
= 36√3
So the area is 36√3 square units.
I cannot be sure of this answer because you did not provide a diagram.
Answer:
Step-by-step explanation:
Factor out a 6 from the numerator and 2 from the denominator
2 in the denominator divides the 6 in the numerator
factor the denominator, let me know if you need help with this
the (x+6)s cancel
