Answer:

x = 4

Step-by-step explanation:

If the lonely negative sign infront of the brackets is confusing, it can be rewritten as -1.

To solve, simplify by expanding then isolate x.

-8 = -( x +4)

-8 = -1 ( x +4) Distribute over brackets by changing the each term's sign

-8 = -x - 4 Start isolating x by moving everything to the other side

-8 +4 = -x -4 + 4 Add 4 to both sides so it cancels out on the right

-4 = -x

-4 = -1x <= -x is the same at -1x

-4/-1 = -x/-1 <=divide both sides by negative 1

4 = x

x = 4 <= usually we write the variable on the left side

Answer:

B. 93%

Step-by-step explanation:

Find the z-score:

z = (x − μ) / σ

z = (122 − 100) / 15

z = 1.47

Find the probability using a calculator or z-score table.

P(Z < 1.47) = 0.93

What is the answer for this below

Likurg_2 [28]

Answer:

8 Units Squared

Step-by-step explanation:

Assuming you meant area, you would first solve for the square, which would be 2 x 2 which is 4. Next, you would solve for both of the triangles, which can be solved by doing 2 x 2 x 1/2, which would be 2. Multiply that 2 by the number of triangles (also 2) and you get 4. Finally, add 4 and 4 to get your final volume of 8.

Calculate the distance between the points H=(3,-1) and E=(8,-5) in the coordinate plane. Give an exact answer (not a decimal app

tester [92]

Answer: $\sqrt{41}$

===========================================

Work Shown:

Use the distance formula.

$d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-1-(-5))^2+(3-8)^2}\\\\d = \sqrt{(-1+5)^2+(3-8)^2}\\\\d = \sqrt{(4)^2+(-5)^2}\\\\d = \sqrt{16+25}\\\\d = \sqrt{41}\\\\$

Or you could use the pythagorean theorem, which is how the distance formula is set up.
