Break the numbers under the radical into perfect squares: $\sqrt{2^2*2^2*2*x^2*x^2*z}$ . Take the perfect squares out: you have two 2's, and 2 x's, on the outside of the radical with 2 and z leftover: $3*2*2*x*x*\sqrt{2*z}$ . Multiply everything together to get $12x^2\sqrt{2z}$ .

11. A line through points (-5, 2) and (2, y) has a slope of 3.<br> Find y.<br> Help

allochka39001 [22]

Answer:

Step-by-step explanation:

Create an equation to find y: 3 = $\frac{y-2}{2-(-5)}$

Calculate by adding: 3 = $\frac{y-2}{7}$

Multiply both sides of the equation by 7 : 21 = y - 2

Move the variable to the left-hand side and change its sign : -y + 21 = -2

Calculate and change signs : y = 23

y = 23

Answer:

Step-by-step explanation:

$-8x-14=7(-2-4x)+4x\qquad\text{use the diastributive property}:\ a(b+c)=ab+ac\\\\-8x-14=(7)(-2)+(7)(-4x)+4x\\\\-8x-14=-14-28x+4x\qquad\text{add 14 to both sides}\\\\-8x-14+14=-14+14-24x\\\\-8x=-24x\qquad\text{add}\ 24x\ \text{to both sides}\\\\-8x+24x=-24x+24x\\\\16x=0\qquad\text{divdie btoh sides by 16}\\\\\dfrac{16x}{16}=\dfrac{0}{16}\\\\x=0$

A set of four numbers that begins with the number 32 is arranged from smallest to largest. If the median is 35, which of the fol

Zielflug [23.3K]

The possible set of numbers will be 32, 35, 36, 35.

It should be noted that when a set of numbers are arranged in either the ascending or the descending order, the median of the numbers will be the number in the middle.

Given the numbers, 32, 35, 36, 35, we have to rearrange them and this will be 32, 35, 35 and 36. Therefore, we can see that the number in the middle is 35 which is the median.

In conclusion, the core option is B.
