NEED HELP PLEASE ANSWER ASAP! (44)

HACTEHA [7]

Answer:

$-3x^2 * x = -3x^3\\y * y = y^2$

$(-3x^2y)(5xy^2 + xy)\\$

Use F.O.I.L, (First Outer Inner Last) to multiply. Start with -3x^y * 5xy^2

Start with similar terms

$-3x^2 * 5x = -15x^3\\y * y^2 = y^3\\Therefore,\\-15x^3y^2$

Move onto the xy portion of the problem

$-3x^2y(xy)\\$

Start with similar terms

$-3x^2 * x = -3x^3\\y * y = y^2\\Therefore,\\-3x^3y^2$

Combine the two together

$-15x^3y^3 - 3x^3y^2\\$

The answer is Option A

How many solutions does the following equation have?<br> 20z – 5 – 12z = 10z + 8

tensa zangetsu [6.8K]

The equation $20z-5-12z = 10z + 8$ have one solution i.e $z=-\frac{13}{2}$

Step-by-step explanation:

Finding the solutions of the equation:

$20z-5-12z = 10z + 8$

Solving:

$20z-5-12z = 10z + 8\\8z-5=10z+8\\Adding\,\,5\,\,on\,\,both\,\,sides\\8z=10z+8+5\\8z=10z+13\\Adding\,\,-10z\,\,on\,\,both\,\,sides\\8z-10z=13\\-2z=13\\z=\frac{13}{-2} \,\,or\\z=-\frac{13}{2}$

The equation $20z-5-12z = 10z + 8$ have one solution i.e $z=-\frac{13}{2}$
