5. Combining like terms is similar to adding and subtracting whole numbers because you just add/subtract the numbers with the same variables. It's different because in normal adding and subtracting, you can do it with any whole numbers. But with combining like terms you have to make sure that each term has the same variable or else you can't add/subtract them.
Answer:
The inside angle b is 50
Step-by-step explanation:
Since the angles of a triangel must = 180 degrees we subtrace 75 from 180 to get 180-75=105 and from there we know that angle a must be equal to angle c so 75+50-125 and then 180-125 = 55 so the inside angle of A must be 55 we get 105 back and subtract 55 from that to get 50 so b is equal to 50

Answer:
To find the left triangle we make the two right triangles equal 1 square, making the area of that 2x2 or 4
Then we take the uppermost triangle on the left and find the area of that which is 2x2 / 2 or 2. Then we find the right uppermost triangle which is 5x 2 /2 or 5. Then we take the rightmost triangle and find that 4x 4 /2 or 8. Then we add the square in the middle which is 3 x 4 or 12.
Add those area 4 + 2 + 5 + 8 + 12. You should get 31.
Hope that helps somewhat. You need to divide the shape into easily usable shapes like squares and triangles.
