you have to apply this formula (a+b)(c-d)=ac-ad+bc-bd

-6a^3*b*5a^2+6a^3b*2ab+6a^3b*b+2ab^2*5a^2-2ab^2*2ab-2ab^2*b=

-30a^5*b+12a^4b^2+6a^3b^2+10a^3b^2-4a^2b^3-2ab^3

(9y +7)=(2y +98)( Because vertically opposite angle is always equal)

9y - 2y = 98-7

9y - 2y = 98-7

7y= 91

y =13

therfore y = 13

(9y + 7)

9*13+7

117+7

124

(2y +98)

2*13+98

26+98

In 3 apples cost 48¢ , how many dozen apples can be bougth for $3.84?

Law Incorporation [45]

1 dozen = 12 apples.

3 apples cost 0.48, multiply that by 4 to get the price of 1 dozen.

0.48 x 4 = $1.92 per dozen.

Divide the total you can spend ( 3.84) by cost per dozen:

3.48 / 1.92 = 2

You can buy 2 dozen.

How do you solve for x? <img src="https://tex.z-dn.net/?f=%20log_%7B6%7D%2836%29%20%20%3D%205x%20%2B%206" id="TexFormula1" ti

The value of x in the given equation is $-\frac{4}{5}$

From the question,

We are to solve the given equation

The given equation is

$log_{6}(36) = 5x +6$

This becomes

$log_{6}(6^{2} ) = 5x +6$

From one of the laws of logarithms, we have that

$log_{x}(x^{2} ) = 2log_{x}(x)$

and

$log_{x}(x) = 1$

∴ $log_{6}(6^{2} ) = 5x +6$ becomes

$2log_{6}(6) = 5x +6$

and

$2(1)= 5x +6$

$2 = 5x +6$

Now, subtract 6 from both sides

$2-6 = 5x +6-6$

$-4 = 5x$

∴ $x = -\frac{4}{5}$

Hence, the value of x in the given equation is $-\frac{4}{5}$
