Ivan

Answer:

6 inches.

Step-by-step explanation:

Let a represent side length of larger square.

We know that area of square is square of its side length, so area of the larger square will be a^2.

The area of smaller square would be 4^2.

We will use proportions to solve our given problem.

\frac{\text{Area of smaller square}}{\text{Area of larger square}}=\frac{4}{9}

\frac{4^2}{a^2}=\frac{4}{9}

\frac{16}{a^2}=\frac{4}{9}

Cross multiply:

4*a^2=16*9

\frac{4*a^2}{4}=\frac{16*9}{4}

a^2=36

Take square root:

a=\pm\sqrt{36}

a=\pm 6

Since the length cannot be negative, therefore, the side length of larger square is 6 inches.

lisabon 2012 [21]

Answer: (10x + 30)

Step-by-step explanation:

1. combine like terms. -4x + 3x = -x

2. you can’t have a negative x, so you would multiply the equation (-x+3) by -1, to get (x-3).

3. (x-3)(10)... 10 • x = 10x, 10 • 3 = 30.

4. put them together, answer would be 10x + 30.
