Rewrite it in the form a^2 - b^2, where a = 7q^2 and b = 2

(7q^2)^2 - 2^2

Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)

= (7q^2 + 2)(7q^2 - 2)

Johnathan makes $27 per hour and works 25 hours per week. Every week, he has to sell 20 items. If he sells more than 20 items in

ser-zykov [4K]

Answer:

Total income = 27 $\times$ 25 + 14% of $1000= $815

Step-by-step explanation:

Number of hours for which Johnathan worked = 25

Salary for each hour = $27

So, income for 25 hours = 25 $\times$ 27 = $675

Now, it is given that he has sold 25 items.

Sales made beyond the 20 items = $1000

Additional income for additional sales = 14% on each set of 5 items

He has sold exactly 5 additional items that means 1 set of 5 additional items.

So, Additional income for additional sales = 14% $\times$ 1000 = $140

Therefore, total income of this week = Income for 25 hours + Income due to additional sales of 5 items

Therefore Total income = 27 $\times$ 25 + 14% of $1000= $815

snow_tiger [21]

Answer:

4h - 20g

Step-by-step explanation:

According to the Distributive Property, you should multiply (distribute) the 4 across the parentheses.

4(h - 5g)

= (4•h) - (4•5g)

= 4h - 20g

Answer:

this is a trick question. The answer would be 67.

It is 67 because 16 dollars he made last week. BUT it says "and now has 67 dollars." that "and" meaning total sum. Maybe I'm wrong but this is my guess.

The derivative of a function f(x) is given by f'(x)=3x^2-6x+4. The tangent line at the point (2,9) is parallel to another tangen

ArbitrLikvidat [17]

Answer:2

Step-by-step explanation:

Given

The derivative of a function is $f'(x)=3x^2-6x+4$

The slope at (2,9) is

$\Rightarrow 3(2)^2-6\times 2+4=4$

the tangent at (2,9) is parallel to another tangent at (a,b) i.e. their slopes are equal

$\Rightarrow 4=3a^2-6a+4\\\Rightarrow 3a^2-6a=0\\\Rightarrow\ 3a(a-2)=0\\\Rightarrow a=0\ \text{or}\ a=2$
