Answer:

x^{2}+5x-36

Step-by-step explanation:

To multiply binomials there are 2 ways. F.O.I.L., or the box method.

I will use the box method, and I hope it helps you!

After looking at the picture, this is not the answer quite yet.

x^{2}+9x-4x\\-36

Subtract 4x from 9x.

9x-4x=5x

So, the answer will be x^{2}+5x-36

Answer:

x^2 + 5x - 36

Step-by-step explanation:

Hello!

For this equation, we are going to multiply both binomials using FOIL.

FOIL stands for:

First

Outside/Outer

Inside/Inner

Last

This tells you the order in which you multiply two binomials in parentheses.

Let's get started!

First: x * x = x^2

Outside: x * -4 = -4x

Inside: 9 * x = 9x

Last: 9 * -4 = -36

x^2 - 4x + 9x - 36

These problems usually involve combining like terms, which is what we have to do here: -4x + 9x = 5x

And there you have it!

x^2 + 5x - 36

If you have any questions, just comment!

Hope I helped!

Someone plz help me 1-1\2c=6
GarryVolchara [31]

1 - 1/2c = 6

1 -1 - 1/2c = 6 -1 (subtract 1 on both sides)

-1/2c = 5 (next do the inverse operation)

c = 5 ÷ 1/2

c = -10

to check your answer substitute the value of c in the equation;

1- 1/2c = 6

1- 1/2(-10) = 6

1 + 5 = 6

6 =6

A cone is filled to a height of 3 inches with a liquid. The liquid is then poured into an empty cylinder with the same height an
Tasya [4]
Answer: 1 inch

Volume of the cylinder = πr²h

Volume of the cone = 1/3πr²h

If the radius are the same for both the cone and the cylinder, then the liquid will reach 1/3 of its height in the cylinder compared to the cone. 

Height = 1/3 x 3 inches 
Height = 1 inch

----------------------------------------------------------------------------------------
Answer: The height of the cylinder will be 1 inch.

S is inversely proportional to t . When s = 0.5 , t = 7 Work out t when s = 5
shtirl [24]

Answer:

t = 0.7

Step-by-step explanation:

s = k/t  where 'k' is the constant of variation

given:  0.5 = k/7 so k = 3.5

5 = 3.5/t

5t = 3.5

t = 0.7

6x — 4 > 14or3х + 10 < 4
Ipatiy [6.2K]

9514 1404 393

Answer:

  x < -2  or  3 < x

Step-by-step explanation:

<u>6x -4 > 14</u>

  6x > 18 . . . . add 4

  x > 3 . . . . . . divide by 6

<u>3x +10 < 4</u>

  3x < -6 . . . . subtract 10

  x < -2 . . . . . divide by 3

The solution is the union of disjoint sets:

  x < -2  or  x > 3
