Step-by-step explanation:
Answer:
1.First Move the decimal point in the divisor and dividend.
2.Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
3.Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Step-by-step explanation:
I got it from google tbh
1. Remove parentheses
-3x^2 + x^4 + x + 2x^4 - 7 + 4x
2. Collect like terms
-3x^2 + (x^4 + 2x^4) + (x + 4x) - 7
3. Simplify
-3x^2 + 3x^4 + 5x - 7
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
The answer is 108cm^2 because it gives you the entire height of the shape minus the height of the rectangle the divide it by two to find the height of the triangles the find the area of all the different shapes then add it together
