Answer:

Option A

Step-by-step explanation:

We are given the values of x, y, and z, which is -1, 2, 5 respectively.

Let us substitute the values into the expression provided to determine a specific numerical value of the expression, when x = -1, y = 2, and z = 5.

⇒ x(-y + z) = x(z - y) = -1(5 - 2)

Finally, let's simplify the expression as necessary.

⇒ -1(5 - 2)

⇒ -1(3)

<u>Integer rule:</u> Any number multiplied by -1 is the number's opposite.

⇒ -3

Therefore, the correct option is "Option A"

6x+12y+5+2y+8 what’s the coefficient of y and what’s the constant
Rudik [331]

The coefficient of y is 14 and the constant is 13.

You can find this by combining like terms first.

6x + 12y + 5 + 2y + 8

6x + 14y + 5 + 8

6x + 14y + 13

Now the coefficient is the number next to y. The constant is the number on its own.

Compute the following radical.<br> sq root 144
lara31 [8.8K]

we are given

\sqrt{144}

Firstly, we will find all possible factors of 144

144=2\times 2\times 2\times 2\times 3\times 3

we can also write as

144=(2\times 2)^2\times (3)^2

now, we can put exponent to over entire term

144=(2\times 2\times 3)^2

now, we can replace 144

\sqrt{144}=\sqrt{(2\times 2\times 3)^2}

now,  sqrt will get cancelled with square

and we get

\sqrt{144}=(2\times 2\times 3)

now, we can simplify it

\sqrt{144}=(4\times 3)

\sqrt{144}=12.............Answer
