Answer:

quadratic equation is 2 degree polynomial

x2 - x -72 = x2 - 9x +8x -72

x(x - 9 ) + 8(x - 9) = (x -9) (x+8)

1st correct - quadratic

2nd correct - quadratic

3rd - it's linear equation, not quadratic

4th - correct - quadratic

$\frac{3(x+5)}{2} \cdot 2=21\cdot 2$

Above step we use "Multiplication property of equality"

$3(x+5)=42$

In the above step we "Simplify on both sides of equation"

$3x+15 = 42$

In the above step we use "Distribution property"

$3x+15-15=42-15$

The above step is the result of using "Subtraction property of equality"

$3x=27$

Above step is result of "Combining the like terms"

$\frac{3x}{3} =\frac{27}{3}$

Above step is the result of using "Division property of equality"

$x=9$

Above step is result of "Simplifying fractions on either side of equation"

Nora can do 70 push ups in 2 minutes. Luke can do 105 push ups in 3 minutes. Do these rates form a proportion? explain

poizon [28]

Yes they do. In order to do this you must make the fraction 70/2 and 105/3. If you divided each one of those you get 35 for both which means it's a proportion.

Use the distributive property to remove the parentheses. <br> -5(-6w+3v-5)

adelina 88 [10]

Answer:

$30w - 15v + 25$

Step-by-step explanation:

Multiply -5 by each term inside the parentheses.

$-5(-6w+3v-5) =$

$= -5 \times (-6w) + (-5) \times 3v + (-5) \times (-5)$

$= 30w - 15v + 25$
