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

Jon is hanging a picture. He wants to center it horizontally on the wall. The picture is 32 1/2 inches long, and the wall is 120
frozen [14]

Answer:

44.125 inches

Step-by-step explanation:

Given that:

Length of picture = 32 1/2 inches

Length of wall = 120 3/4 inches

Hence, to center picture horizontally ;

Distance from the edge of the wall in which the picture should be placed :

(Length of wall - length of picture) / 2

(120 3/4 - 32 1/2) / 2

(483/4 - 65/2) / 2

Take the L. C. M of 4 and 2 = 4

((483 - 130) / 4) ÷ 2

(353 / 4) ÷ 2

(353 / 4) * (1 / 2)

= 353 / 8

= 44 1/8

= 44 1/8

= 44.125 inches

In triangle PQR, p equals what.
Darina [25.2K]
The correct answer is 3.

The formula for the law of sines is the following:

P/sin P = Q/sin Q = R/sin R

So, if you break these up into two different equations, you will have: 

P/sin P = Q/sin Q and P/sin P = R/sin R

To solve, get P alone on one side of the equation by multiplying the other side by sin P:

P = Q sin P/sin Q and P = R sin P/sin R

When you look at the answers, you'll see that the second equation is an option.

oyce is trying to solve the equation y = x2 − 8x + 7 using the quadratic formula. She has made an error in one of the steps belo
Naddik [55]

You didn't attach anything, but this is how you should solve this equation: given an equation ax^2+bx+c=0 the solutions are

x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

In your case, the values are a=1,\ b=-8,\ c=7. If you plug these values inside the solving formula, you have

x_{1,2} = \dfrac{8\pm\sqrt{64-4\cdot 1\cdot 7}}{2\cdot 1} = \dfrac{8\pm\sqrt{64-28}}{2} = \dfrac{8\pm\sqrt{36}}{2} = \dfrac{8\pm6}{2} = 4\pm3

So, the two solutions are 1 and 7
