Answer:

D. 2x² + 10x - 2

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Length = x² + 3x - 2

Width = 2x + 1

Perimeter = 2(x² + 3x - 2 + 2x + 1)

Perimeter = 2(x² + 5x - 1)

Perimeter = 2(x²) + 2(5x) - 2(1)

Perimeter = 2x² + 10x - 2

Question 3 1 Marge is making a chocolate cake to surprise the best nend. She needs 3 1/2cups of four but she only has 1/3cup. Ho

AfilCa [17]

Answer:

19/6 cups

Explanation:

First, we need to transform the mixed number into a fraction as:

$3\frac{1}{2}=\frac{3\cdot2+1}{2}=\frac{7}{2}$

Now, we need to subtract 1/3 from 7/2, so:

$\frac{7}{2}-\frac{1}{3}=\frac{7\cdot3-2\cdot1}{2\cdot3}=\frac{21-2}{6}=\frac{19}{6}$

Therefore, she needs 19/6 cups more
