Mario is constructing a square dart board. It will consist of a smaller square centered in a larger square. The smaller square m

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.

What is the product of the polynomials below

Scrat [10]

Answer:

B. $15x^{4}$ + 2x³ - 8x² - 22x - 15

Step-by-step explanation:

1. (3x² - 2x - 3)(5x² + 4x +5)

$15x^{4}$ + 12x³ + 15x² - 10x³ - 8x² - 10x - 15x² - 12x - 15

2. Combine like terms

$15x^{4}$ + 2x³ - 8x² - 22x - 15

Carlotta handpaints T-shirts and sells them to her friends. She uses the equations below to determine her costs and the amount o

spayn [35]

Profit = Income - cost
Profit = 10s - (28 + 3s) = 10s - 28 -3s = 7s - 28.

Profit = 0

0 = 7s - 28

7s = 28
7s = 28/7
s = 4. This is the breakeven point.

Carlota must sell more than 4 shirts to make a profit
