Simplifying that would be 3 * (-7) -10+25 = -6. Combining like terms will get us to -21 +15 = -6, going further will be -6 = -6. Remember Order of Operations. Since -6 = -6, the equation is true.

What is log15 2^3 rewritten using the power property?

OlgaM077 [116]

ANSWER

$log_{15}( {2}^{3} ) = 3 \: log_{15}( {2} )$

EXPLANATION

According to the power property of logarithms:

$log_{x}( {y}^{n} ) = n \: log_{x}( {y} )$

The given logarithm is

$log_{15}( {2}^{3} )$

When we apply the power property to this logarithm, we get,

$log_{15}( {2}^{3} ) = 3 \: log_{15}( {2} )$

The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)

<h3>What is an expression?</h3>

An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division

x^3 – 7x^2 – 5x + 35

factor the given equation

x^2(x – 7) – 5(x - 7)

Factor out x - 7

(x^2 - 5)(x - 7)

Therefore, the factored expression is (x^2 - 5)(x - 7)

2. Elena finds that the area of a house on a scale drawing is 25 square inches. The

likoan [24]

Answer:

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of an house on a scale drawing in square inches

y ---> the actual area of the house in square feet

$z^2=\frac{x}{y}$

we have

$x=25\ in^2$

$y=2,025\ ft^2$

substitute

$z^2=\frac{25}{2,025}$

simplify

$z^2=\frac{1}{81}$

square root both sides

$z=\frac{1}{9}\ \frac{in}{ft}$

therefore

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$
