Using rule of exponents 

Using rule of exponents 


To equalize the negative sign, we'll move t to the denominator

-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
Y-b/m=x (you just move everything to the other side)
<u>Statement</u><u>:</u>
The base of a triangle is 3m and its height is
m.
<u>To </u><u>find </u><u>out:</u>
The area of the triangle.
<u>Solution:</u>
- Given, base = 3m, height =
m - We know,

- Therefore, the area of the triangle

Answer:
2x + 3t - 4
Step-by-step explanation:
Hi,
To simplify the expression, we must combine like terms. To start, let's combine all of the x-values.
4x + 3t - 2x - 4
When we combine 4x and -2x we get 2x.
2x + 3t - 4
We can't combine anything else. They don't have the same variables and 4 doesn't even have a variable, so 2x + 3t -4 is the simplified expression.
I hope this helps :)
