Answer:
y(4 + z)
Step-by-step explanation:
Here in this problem, we have to rewrite the expression y • 4 + y • z without using the grouping symbols.
Now, we can assume that '•' symbol here represents the multiplication symbol.
So, there are two parts of the expression and in both of the parts, y is multiplied. Hence, we can take common y from both parts.
So. y • 4 + y • z = y(4 + z).
Therefore, option c matches the result. (Answer)
Where’s the rest of the problem
A. The ratio of white tiles to purple tiles is 4 to 5.
B. It has 800 white tiles. 4/5 x 200 = 800/1000.
C. The ratio of white tiles to all tiles is 12 to 27, I think.
D. 1284 white tiles, 12/27 x 107 = 1284<span>/2880.</span>
