Answer:

x = 4

Step-by-step explanation:

First u need to distribute the -1 to (x + 4), creating the equation, -8 = -x - 4. Then add the -4 to both sides, and you get, -4 = -x. Then divide by -1 to both sides, and x = 4.

-8=-(x+4)

Pretend that there is a -1 in front of the bracket.

Multiply the bracket by -1

(-1)(x)(-1)(4)

-8=-x-4

Move -4 to the other side. Sign changes from -4 to +4.

-8+4=-x-4+4

-4=-x

Multiply both sides by -1 to get +x.

-4(-1)=(-x)(-1)

x=4

Answer: x=4

Use Heron's formula to find the area of the triangle. Round to the nearest square foot.
Sphinxa [80]

Answer:

A ≈ 2 ft²

Step-by-step explanation:

The area (A) of a triangle using Heron's formula is

A = \sqrt{s(s-a)(s-b)(s-c)}

where s is the semiperimeter and a, b , c the sides of the triangle.

s = \frac{a+b+c}{2} = \frac{4+4+1}{2} = \frac{9}{2} = 4.5

Then

A = \sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}

   = \sqrt{4.5(0.5)(0.5)(3.5)}

   = \sqrt{3.9375}

   ≈ 1.9843...

   = 2 ft² ( to the nearest square foot )

I just need someone to explain how to do it
Mashutka [201]
You just need to substitute the the given function. So if f(-8) then you fill in f(n)=2n+4 which would be f(-8)=2(-8)+4. Which is -12.

hope this helps !

What is the solution to this equation? x + (- 14) = 4. (A) x = 10. (B) x = - 10. (C) x = - 18. (D) x = 18
Vika [28.1K]
First, you want to get x by itself on one side. We write the equation as x-14=4. Since 14 is being subtracted from x, we add it to both sides to cancel it out, x-14+14=4+14 or x=18.

Your answer would be D.
