What is the mathematical reasoning for Step 3?

4 0

Based on the operation in step 3, the mathematical reasoning that we see is the Associative property.

<h3 /><h3>What is the reasoning in step 3?</h3>

Step 2 was:

= 3/4x (-8x) + (3/4x) (6)

Step 3 then became:

3/4 x (-8) × x × x  + 3/4 x 6x

This shows the associative property because the numbers were regrouped but because they are being multiplied by each other, the result will not change.

Answer:

(a) 9x^2+16x-4

(b) 9a(2a+5)

(c) (y-6)(y-4)

Step-by-step explanation:

(a)

(9x-2)(x+2)=

9x^2-2x+18x-4=

9x^2+16x-4

(b)

18a^2+45a=

9a(2a+5)

(c)

y^2-10y+24=

(y-6)(y-4)

A 3-gallon bottle of fabric softener costs $33.24. What is the price per quart?
asambeis [7]

Answer:

$2.77 per quart.

Step-by-step explanation:

There are four quarts in a gallon.

4 * 3 = 12

There are 12 quarts in 3 gallons.

\frac{price}{quart} =\frac{33.24}{12}=\frac{33.14/12}{12/12}=\frac{2.77}{1}=\boxed{2.77}

The price per quart should be $2.77.

Hope this helps.

Find each unknown angle measurement.
Alex Ar [27]

Answer:

angle(2) = 118 degree

angle(3) = 118 degree

angle(4) = 62 degree

Step-by-step explanation:

To find angle 2 :

62   + angle{2} = 180 \\ angle{2} = 180 - 62 = 118 \: degree

The rule (head to head):

angle(2) = angle(3) = 118 degree

And the last one is angle(4) which is the same thing:

angle(4) = angle(1) = 62 degree

Drag the tiles to the correct boxes to complete the pairs. Match each expression to the correct verbal description. 8 added to t
QveST [7]

Answer:

<u>A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed</u>

<u>B. 7x³ + 8 ⇔ 8 added to cube of 7x</u>

<u>C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8</u>

<u>D.  (7x + 8)³ ⇔ the cube of the sum of 7x and 8</u>

Step-by-step explanation:

1. Let's drag the tiles to the correct boxes to complete the pairs.

A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed

The second tile was already given and solved, however we're copying it.

B. 7x³ + 8 ⇔ 8 added to cube of 7x

C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8

We use the expression 7 times because number 7 is multiplying the sum inside the parenthesis.

D.  (7x + 8)³ ⇔ the cube of the sum of 7x and 8
