Answer:

Area: 40 cm²

Perimeter: 24 cm

Step-by-step explanation:

<u>Area of Triangle</u>

To find the area of a triangle, you need to do 1/2bh.

b*h = 80. Divide by 2, you get 40 cm²

<u>Perimeter of Triangle</u>

Just add up all the sides! 10 + 8 + 6 = 24 cm!

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!

Which inequality can be used to represent a number x that is less than equal to 8 and greater than -3
KIM [24]

Answer:  x =  -2,-1, 0, 1, 2, 3, 4, 5, 6, 7, 8

Solution:

A number line is used to represent the possible numbers that x can be.

x that is less than equal to 8 >>>> x ≤ 8

x is greater than -3 >>>>  x > -3

So it will be represented as,

  -3 < x ≤ 8

So all the numbers between  -3 and 8 including eight (because it has the equal sign)

-2,-1, 0, 1, 2, 3, 4, 5, 6, 7, 8

What equation represents a parabola with a focus of (0,4) and a directrix of y=2
scZoUnD [109]
We know that

Any point <span>(x,y)</span> on the parabola is equidistant from the focus and the directrix

Therefore,

focus (0,4) and directrix of y=2

<span>√[<span>(x−0)</span></span>²+(y−4)²]=y−(2)

<span>√[x</span>²+(y-4)²]=y-2

x²+(y-4)²=(y-2)²

x²+y²-8y+16=y²-4y+4

x²=4y-12-----> 4y=x²+12----->y= (x²/4)+3


the answer is

y= (x²/4)+3
