You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.

Answer:
r can be 0.5
Step-by-step explanation:
Here, we want to get a possible value of r
From the question, the value of r is between 0 and 3
Mathematically, we know that in degrees pi is the same as 180 degrees
In a case where we have r = 1/2
we have it that;
cos(pi/2) = 2 cos (pi/2)
Since pi/2 is 90 and cos 90 is zero; then we have it that the two sides of the equation is the same and r can be 1/2
Cuz 14/4 and 56/16 are equal ... just divide both of them and you get 3.5 for both
if you multiply both the denomintor and numerator of 14/4 by 4 you get 56/16 so that's how u know they're equal because if you multiply both by the same number you should get a fraction equal to that one

Answer:
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
Step-by-step explanation:
630 ÷ 7 ÷ 2 ⋅ 9 ⋅ 25 = 125
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
90 ÷ 18 ⋅ 25 = 125
5 ⋅ 25 = 125
125 = 125
