Answer:

The expression 3x+13 represents the side length of the square in units.

Step-by-step explanation:

Let the a be the side length of the square in units.

The perimeter of a square is

$P=4a$

It is given that a square has a perimeter of 12x+52 units. Substitute P=12x+52 in the above formula, to find the expression that represents the side length of the square in units.

$12x+52=4a$

Divide both sides by 4.

$\frac{12x+52}{4}=\frac{4a}{4}$

$\frac{12x}{4}+\frac{52}{4}=a$

$3x+13=a$

Therefore expression 3x+13 represents the side length of the square in units.

Which equation is equivalent to the given equation? x^2 - 10x = 14

ArbitrLikvidat [17]

Answer:

(x - 5)² = 39

Step-by-step explanation:

Given

x² - 10x = 14

To obtain an equivalent equation use the method of completing the square.

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 5)x + 25 = 14 + 25

(x - 5)² = 39

G=b(a + D2)<br><br> Solve for A

Katyanochek1 [597]

Answer:

$a = \frac{g}{b} - D_{2}$

Step-by-step explanation:

Given the literal equation, $g = b(a + D_{2})$

To solve for a:

Multiply both sides of the equation by $\frac{1}{b}$ :

$(\frac{1}{b}) g = (\frac{1}{b}) b (a + D_{2})$

$\frac{g}{b} = a + D_{2}$

Next, subtract $D_{2}$ on both sides of the equation to solve for a:

$\frac{g}{b} - D_{2} = a + D_{2} - D_{2}$

$\frac{g}{b} - D_{2} = a$

Here are the two methods you can perform this question :Method 1:
Probability that they are boys: 0.528 (4 squared) = 0.0777205Probability that 1 is a girl: 1 - 0.0777205 = 0.9222795 = 92.22%
Method 2:n=4p(boys)= 0.5281-o.528 = 0.9222795= 92.22%
