The perimeter:
P=2\cdot(3x+3)+2\cdot2x=6x+6+4x=10x+6\\\\P=146\ units\to10x+6=146\ \ \ |-6\\\\10x=140\ \ \ |:10\\\\x=14\ units
The length of the longer side:
3x+3=3\cdot14+3=42+3=45\ units

Help with 3 show work please
schepotkina [342]
Alright assuming they mean total surface area since they didn't say lateral the equation to follow would be S= Ph + 2B

Start with P:
P stands for perimeter, so add up all the edges on one face of the cube.


17 + 17 + 17 + 17 = 68
Then your equation becomes
S= 68×h + 2B
h=height and that's obviously 17
so, S= 68×17 +2B

Now to find B. This is pretty easy. All you need to do is take 17×17 because you're finding the area of the base. This equals 289.

Finally this leaves us with the equation
S= 68×17+2×289

From there on you just solve it out.
This would leave you with 1734.

The vertex of the graph of y = -4(x + 3)2 + 2 is ( , )
andrezito [222]

Answer:

Step-by-step explanation:

This quadratic is of the form

y=-a(x-h)^2+k where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).

56% enrolled if a same of 500 is randomly selected what probability 250 will get selected?​
dalvyx [7]

I'll get you started:

mean = np = (500)(.56) = ?

standard deviation = √npq = √(500)(.56)(.44) = ?

Note: q = 1 - p

Finish the calculations.

To find z-score:

z = (x - mean)/sd

Note: x = 250

Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.

10. What is the value of x in the solution to the system of equations?
RUDIKE [14]

Solve for x in first equation:

x-2y=7

Add “2y” to both sides

x=2y+7

Put this in to second equation:

3(2y+7)+2y=21

Solve for y:

Distribute the 3 into the ()

6y+21+2y=21

Combine the like y terms

8y+21=21

Subtract 21 from both sides

8y=0

Divide by 8 on both sides

y=0

Put this into the first solved equation:

x=2(0)+7

Solve for x:

Multiple 2(0)

x=0+7

Add 0 and 7

x=7

So the value of x is positive 7.
