Hey there!

The product of a number and 18 means you multiply that number times 18; the result is called the product.

When we multiply a number times a variable, we always write the number before the variable.

For example, we multiply 4 times d, and the result is 4d.

Let's check the options and see if we can spot something like "5a"

The first option:  we multiply 18 times the difference of b and 18.

The second option: we add 18 and b

The third option: we divide 18 by b

The fourth option: we multiply 18 times b (That's the right option! We did it  :)

Hence, the answer is

\boxed{\boxed{\bold{18b}}}

Hope everything is clear.

Let me know if you have any other questions; if so, please comment.

Which are the solutions of the quadratic equation?
Artemon [7]

Answer:

x_1=\frac{7+\sqrt{65}} {2}

x_2=\frac{7-\sqrt{65}} {2}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}=7x+4  

equate to zero

x^{2}-7x-4=0  

so

a=1\\b=-7\\c=-4

substitute in the formula

x=\frac{-(-7)\pm\sqrt{-7^{2}-4(1)(-4)}} {2(1)}

x=\frac{7\pm\sqrt{65}} {2}

therefore

x_1=\frac{7+\sqrt{65}} {2}

x_2=\frac{7-\sqrt{65}} {2}

StartFraction 7 minus StartRoot 65 EndRoot Over 2 EndFraction comma StartFraction 7 + StartRoot 65 EndRoot Over 2 EndFraction

If I roll two six-sides dice, what is the probability that the sum of the numbers that show up on the dice is 3 or less?
liq [111]

Answer:

1/12

Step-by-step explanation:

first we have to find all the possibilities of getting a sum of 3 or less: 1+1 or 1+2 and we count the second combination 2 times because the numbers can be on either of the dices so we have a total of 3 possibilities. all the possible pairimg of dice are 6*6=36 because each dice has 6 sides and we can get either of them. so the probability would be the chance of getting a sum of 3 or less divided by all the diff combination which equals 3/36 or 1/12 which is roughly around 8.3%
