Answer:
1. Multiply, or distribute, the outer term to the inner terms.
2. Combine like terms.
3. Arrange terms so constants and variables are on opposite sides of the equals sign.
4. Solve the equation and simplify, if needed
Step-by-step explanation:
The angle of NPR is 130°
First, set up an equation to find x.
Then, solve the equation for x.
Then, substitute 25 in for x in 2x
50
Finally, subtract 50 from 180 to find the angle of NPR
130°
Answer:
area = 240 in²
Step-by-step explanation:
each triangle area = 1/2(4)(15) =30 in²
30 x 8 = 240 in²
Yes it x2 is a factor because at some point and time 2x would cross 4x
