Answer:

<u>commutative property of addition </u>

<u>distributive property</u>

Step-by-step explanation:

Identify the properties used for the first two steps in simplifying 6ab2 + 4a2b – 3ab2 + 3a2b – 2a2b2.

6ab2+4a2b-3ab2+3a2b-2a2b2 = 4a2b+3a2b-3ab2+6ab2-2a2b2 -<u>commutative property of addition</u>

= (4+3)a2b+(-3+6)ab2-2a2b2  

 = 7a2b+3ab2-2a2b2 -<u>distributive property</u>

The expression 6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2 has two similar pairs of <span>conjunctions.
</span>
1. Rewrite this expression as
6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2=
=(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2
and then 
2. add the similar <span>conjunctions
</span><span>
</span><span>(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2=3ab^2+7a^2b-2a^2b^2.</span><span>

Given the function h(x) = x2 – 7x + 6, determine the average rate of change of
guapka [62]

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(h(7) - (h(3)) / (7 - 3)

h(7) = 7² - 7×7 + 6 = 49 - 49 + 6 = 6

h(3) = 3² - 7×3 + 6 = 9 - 21 + 6 = -6

7 - 3 = 4

(6 - -6)/4 = 12/4 = 3

the average change rate in that interval is 3 (or fully 3/1).

How can you use volume formulas to solve problems?
Katarina [22]
Well, it depends what shape you are using the volume formula for. If it's for a square (I'm assuming) then the volume formula would be:

The length of a rectangular garden is 8m greater than twice the width the area of the garden is 280m^2 what is the width of the
yarga [219]

Step-by-step explanation:

Given :-

The length of the garden 8m greater than 2 times the width.

Area of the garden is 280 m²

Let us consider the length as x and width as y.

Sp, we can day length as :-

x = 8 + 2y ---(1)

Now, we know that:-

Area of Rectangle = Length × Breadth

280 = x * y

We can replace the value of x now,

280 = y × ( 8 + 2y)

280 = 8y + 2y²

2y² + 8y - 280 = 0

y² + 4y - 140 = 0

Factorise it.

(y -10)(y + 14)

Cancelling -ve value, we get the width as 10 metres.
