Answer:

the probability of rolling two 6's is 2 out of 12 or 0.167 rounded to the nearest thousandth

Step-by-step explanation:

there are 6 sides on a cube so that's 5 other chances that you'll get 1-5 and having two cubes doubles the chance.

If s(x)=x-7 and t(x) =4x^2+3 which expression is equivalent to (t×s)(x)

marshall27 [118]

Answer:

$\large\boxed{(t\times s)(x)=4x^3-28x^2+3x-21}$

Step-by-step explanation:

$s(x)=x-7\\t(x)=4x^2+3\\\\(t\times s)(x)=t(x)\times s(x)\\\\\text{Substitute:}\\\\(t\times s)(x)=(4x^2+3)(x-7)\\\\\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(t\times s)(x)=(4x^2)(x)+(4x^2)(-7)+(3)(x)+(3)(-7)\\\\=4x^3-28x^2+3x-21$

Find the value of x<br> A.25<br> B.85<br> C.75<br> D.105

Masteriza [31]

Answer:

The value of x is 75

Step-by-step explanation:

First we need to find the other angle that doesn't have a number in it.

To find the degrees of the other angle we subtract 155 from 180.

180 - 155 = 25

Now we have to find the value of x. Add 80 and 25 together to get 105. A triangle is going to be 180 degrees. Subtract 105 from 180.

180 - 105 = 75

Now we will add 80, 25, and 75 to check our work.

80+25+75 = 180

Step-by-step explanation:

we are simplifying

2x-(-8)-7x+4+10=

2x+8+-7+4+10=

2x+8+-7x+4+10

(2x+-7)+(8+4+10)= -5x+22
