you would have 32 multiplication and 16 addition I believe because.
2 2x2 matrices Is 8 multiplication and 4 addition
Answer:
y = 4
Step-by-step explanation:
Use the distributive property to multiply all terms in the parentheses by 4
You will get (8 - 8 + 4y) = 0
Then, 4y = 0
Divide each side by 4 to get
y = 4
Answer:
x = 0
Step-by-step explanation:
Since the product is not equal zero, we need to multiply both parenthesis first:
Add 27 from both sides:
Factor 
out:
Apply the zero product:
The solutions of the equation are 
and 
.
We can conclude that the correct answer is x = 0.
Answer:
C) All squares are rhombuses. Rhombeses have 4 sides that are the same length. Therefore, all squares have 4 sides that are the same length.
Step-by-step explanation:
The answer is C.
If you multiply the top equation by 3 the x variable would become 2x * 3 = 6x
Multiplying the second equation by 2 the x variable becomes -3x * 2 = -6x
You would then have 6x - 6x, which would eliminate the x variable.
