Answer:

$\bf\pink{(2a+3b)\times (1+2a-3b)}$

Step-by-step explanation:

<h2><u>Given Expression</u> :-</h2>

$\sf\orange{2a+ 3b + 4a^2 - 9b^2}$

<h2><u>Steps to factorise</u> :-</h2>

$\hookrightarrow\:\:\:\sf\purple{2a+ 3b + 4a^2 - 9b^2}$

Using a²-b² = (a-b)(a+b), factor the expression

$\hookrightarrow\:\:\:\sf\red{2a+3b+(2a-3b)\times (2a + 3b)}$

Factor out 2a+3b from the expression

$\hookrightarrow\:\:\:{\boxed{\sf{\pink{(2a+3b)\times (1+2a-3b)}}}}$

Add 5/9+7/9 . Simplify the answer and write a mixed number

Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

$\frac{5}{9}+\frac{7}{9}=\frac{12}{9}$

Then you reducing by the fraction parts of 12/9.

$\frac{12}{9}=\frac{4}{3}$

And finally, you simplify by the fraction parts of 4/3.

$\frac{4}{3}=1 \frac{1}{3}$

Solution by Formulas

Applying the fractions formula for addiction.

$\frac{(5*9)+(7*9)}{9*9}$

$\frac{45+63}{81}$

$=\frac{108}{81}$

Simplifying 108/81 and the answer is

$=1 \frac{1}{3}$

Hope this helps!

How do i solve y= -5 in lines in the xy plane ? im confused .

Ilia_Sergeevich [38]

Answer:

see the explanation

Step-by-step explanation:

we know that

The equation of a horizontal line is equal to the y-coordinate of the point that passes through it

In this problem we have

$y=-5$

This is a horizontal line (parallel to the x-axis)

The slope of this line is equal to zero

All points that pass through the line will have the same y-coordinate equal to -5

see the attached figure to better understand the problem
