answer

x = 2

x = -3

step-by-step explanation

4x^2 + 3x = 24 – x move all terms to one side

4x^2 + 4x = 24

4x^2 + 4x - 24 = 0 divide each side by 4

x^2 + x - 6 = 0/4 = 0

factor x^2 + x - 6 by finding two number whose product is -6 and sum is x

(x-2)(x+3) set each term equal to 0 and solve for x

x-2 = 0, x = 2

x+3 = 0, x = -3

What are the partial products that result from multiplying 15x32?

pashok25 [27]

The answer to this question would be: 300; 20; 150; 10

When you multiply 15 x 32, you can divide both numbers into this:
15= 10 + 5
32= 30 +2

Then the multiplication becomes (10+5) * (30+2) which will result in 4 partial product like this:
10*30= 300
10* 2= 20
5* 30= 150
5* 2= 10

How do you solve f(x) = x2 + x - 20?

Darina [25.2K]

$\huge \bf༆ Answer ༄$

Let's solve ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: {x}^{2} + x - 20$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: {x}^{2} + 5x - 4x - 20$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:x(x + 5) - 4(x + 5)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:(x + 5)(x - 4)$

It's factorized now ~ And if you want to find the zeros then equate the expression with 0.

And you will get ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:x = - 5 \: \: and \: \: 4$

Including 5% sales tax, an inn charges $252 per night. Find the inn’s nightly cost before the tax is added

stira [4]

Hi,

To find the cost before tax, we must find out how much the tax is. So we multiply 252 x .05 to get 12.6. So we know the tax was 12.6 dollars. Now all we have to do is subtract that from the total to get our answer. 252 - 12.6 = 239.4.

Have a great day!
