Please help<br> 15x ^2 −4x−4= ?
oksian1 [2.3K]
<h3>I'll teach you how to solve 15x ^2 −4x−4</h3>

--------------------------------------------------------

15x ^2 −4x−4

Break the expressions into groups:

(15x^2+6x) + (-10x-4)

Factor out 3x from 15x^2+6x:

3x(5x+2)

Factor out -2 from -10x-4:

-2(5x+2)

3x(5x+2) -2(5x+2)

Factor out common term 5x+2:

(5x+2)(3x-2)

Your Answer Is (5x+2)(3x-2)

plz mark me as brainliest :)

In parallelogram ABCD , m∠A=(2x)° and m∠B=(5x+5)° . The figure shows parallelogram A B C D with vertices named clockwise from bo
lara [203]

Answer:

The measure of angles of parallelogram are

∠A = 50° ,

∠B = 130° ,

∠C = 50° ,

∠D = 130°

Step-by-step explanation:

Given as for a parallelogram :

The vertices of parallelogram is A B C D in clockwise

The measure of angle A = ∠A =  ( 2 x )°

The measure of angle B =  ∠B =  ( 5 x + 5 )°

Now, for a parallelogram , the sum of measure of all four angles = 360°

<u>From The property of Parallelogram</u>

A ) The adjacent angles are supplementary

So, ∠A + ∠B =  180°

Or, ( 2 x )° + ( 5 x + 5 )° = 180°

Or, ( 7 x + 5 )° = 180°

Or , ( 7 x )° = 180° - 5°

Or , ( 7 x )° = 175°

∴   x = \frac{175}{7}

I.e x = 25°

So,  ∠A =  ( 2 x )° =  ( 2 ×25° )

I.e , ∠A = 50°

 ∠B =  ( 5 x + 5 )°

Or, ∠B =  ( 5 ×25° + 5 )°

I.e ,  ∠B = 130°

B ) The opposite angles of parallelogram is equal

   So,  ∠C =  ∠A = 50°

I,e   ∠C = 50°

And ∠D = ∠B = 130°

I.e  ∠D = 130°

Hence The measure of angles of parallelogram are ∠A = 50° , ∠B = 130° , ∠C = 50° , ∠D = 130°  Answer
