Step-by-step explanation:

3(x + 4) =  - 18 \\ (x + 4) =  \frac{ - 18}{3 }  \\ (x + 4) =  - 6 \\ x =  - 6 - 4 \\ x =  - 10

Answer:

x = -10

3(x + 4) = -18

3x + 12 = -18

3x + 12 = -18

3x = -18-12

3x = -30

x= -30/3

x = -10

The area of the triangle is 28.7 square centimeters. What is the base length of the triangle in centimeters?
Montano1993 [528]

In order to derive the base of a triangle from its area, you need its height as well.

In fact, if we solve the area formula for the base, we have

A=\dfrac{bh}{2} \iff 2A = bh \iff b=\dfrac{2a}{h}

So, the base length would be

b=\dfrac{2\cdot 28.7}{h} = \dfrac{57.4}{h}

where h is the height relative to the base you're interested in.

Solve and check 8-(6-8x) =4x+4
navik [9.2K]
Greetings!

"Solve and check 8-(6-8x)=4x+4"...

Solve for x<span>:
</span>8-(6-8x)=4x+4
Remove the Parenthesis.
8-6-8x=4x+4
Simplify.
2-8x=4x+4
Add -4 to both sides.
(2-8x)+(-4)=(4x+4)+(-4)
Simplify.
-2-8x=4x
Add 8x to both sides.
(-2-8x)+8x=(4x)+8x
Simplify.
-2=12x
Divide both sides by 12.
(-2)/12=(12x)/12
Simplify.
-0.166666667=x

The answer is: <em>x=-0.166666667

</em>Hope this helps.

Point O is the center of the circle. What is the value of X? <br> Answer options: 24, 15, 27, 20
Tanya [424]

Answer: FIRST OPTION

Step-by-step explanation:

To solve this problem you must apply the Intersecting Secant-Tangent Theorem. By definition, when a secant line and a tangent lline and a secant segment are drawn to a circle from an exterior point:

(Tangent\ line)^2=(Secant\ line)(External\ Secant\ line)

The total measure of the secant shown is:

18+Diameter

If the radius is 7, then the diameter is:

D=7*2=14

Therefore:

Secant\ line=18+14=32

You also know that:

External\ Secant\ line=18\\Tangent\ line=x

Keeping the above on mind, you can substitute values and solve  for x:

x^{2}=32*18

x=\sqrt{576}\\x=24
