Answer:
This equation is false.
Step-by-step explanation:
27x15=405
You're doing the distributive property here so you're supposed to add but they subtract. Since you're doing 20x15 you have to add because 27-20=7.
Answer:
I Think it's 6
Step-by-step explanation:
Answer:
all real numbers except x=-3
Step-by-step explanation:
Perhaps you want the domain of ...
(8 -x)/(7x +21)
The domain is all real numbers except the one that makes the denominator zero: x = -3.

Step-by-step explanation:
Step 1:
Let us consider the given expression 
On Right Hand Side of equation,

Using BODMAS rule, we could get 2.4 as value.
Step 2:
Now let us consider the Left Hand Side of equation and solve it
which will be equal to 2.4.
Answer:
16.
How to find... ↓
The small triangle is 1/3 size of the big triangle.
If this is the case, find the LCF here, 4, and multiply each angle's value by the least common factor, 4.
3 x 4 (bottom) = 12
5 x 4 (right side) = 20
4 x 4 (left side <em>the missing side) </em>= 16
Therefore,
The missing side value, <em>x</em>, is 16.
