Using the distributive property,
-4 times 9z = -36z
-4 times -2 = 8

-36z + 8

We cannot simplify it any more, so your answer is simple: -36z+ 8

We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer

Use the distance formula to find the perimeter of the triangle below. Round you answer to the nearest hundredth.

Murrr4er [49]

jAlright, let's take this problem step-by-step:

What is the perimeter:

⇒ all the side-lengths added up

⇒ need to find side-length using distance formula

$Distance_._. Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

- (x₁,y₁): first point

- (x₂,y₂): second point

Let's solve:

Find length of AC

⇒ first point: (5,7)

⇒ second point: (3,3)

$Distance =\sqrt{(3-5)^2+(3-7)^2} =\sqrt{4+16} =\sqrt{20} =4.472$

Find length of AB

⇒ first point: (5,7)

⇒ second point:(8,6)

$Distance=\sqrt{(8-5)^2+(6-7)^2} =\sqrt{9+1} =\sqrt{10}=3.162$

Find length of BC

⇒ first point: (8,6)

⇒ second point: (3,3)

$Distance = \sqrt{(3-8)^2+(3-6)^2} =\sqrt{25+9} =\sqrt{34}=5.831$

Now let's solve for the perimeter:

$Perimeter = 4.472+ 3.126+ 5.831=13.429$

Answer: 13.43 (rounded to the nearest hundredth)

Hope that helps!

Diego is solving the inequality 100 − 3x ≥ -50. He solves the equation 100 − 3x = -50 and gets x = 50. What is the solution to t

andre [41]

Answer:

x≤50

Step-by-step explanation:

100-3x≥-50

subtracting 100 at both side on inequality

-100+100-3x≥--50-100

-3x≥-150

Dividing both sides by 3

-3x/3≥-150/3

-x≥--50

Adding 50 on both sides

-x+50≥-50+50

-x+50≥0

Adding x on both sides

-x+x+50≥0+x

50≥x

so,

x≤50
