Answer:

1. 12 x 6 = 72 area of parallelogram: B x H (BH)

2. 15 + 23 = 38 x 10 = 380 divided by 2 = 190 area of trapezoid: (B1 + B2) x Height x 1/2 (basically dividing by 2)

3. 8 - 2 = 6 (b1) for the trapezoid, 6 (b1) + 8 (b2) = 14 x 4 (height) = 56 divided by 2 (multiplying 1/2) = 28. (Area of the triangle in the figure) 4 x 4 = 16 divided by 2 = 8. 28 + 8 = 36

Using the formula of a triangle: BH x 1/2 (basically dividing by 2)

How many solutions are there to the equation below?

Effectus [21]

Answer:

C. 1

Step-by-step explanation:

Given:

$\displaystyle \large{\sqrt{\sqrt{\sqrt{x}}} = 16}$

The equation can be rewritten as:

$\displaystyle \large{\sqrt[8]{x} = 16}$ via surd property.

Since it’s an even surd, that means there only exists zero-positive numbers for value of x.

To solve this surd equation, simply clear out the surd by powering both sides by 8:

$\displaystyle \large{\left(\sqrt[8]{x}\right )^8=(16)^8}$

Cancel the surd:

$\displaystyle \large{x=16^8}$

Now, evaluating 16^8 will give up a million and that’s not necessary because we are finding how many solutions this equation has. Since theee only exists one value of x, which is the solution to this equation. Therefore:

Your answer is 1 solution

PLEASE HELP ME!!!!!!!!!!

Svetlanka [38]

V = r + at (solve for a).

You want to isolate a. First subtract r.

v - r = at

Divide by t.

(v - r)/t = a

The answer is a = $\frac{v - r}{t}$ .

2/3x+6=1/2x+1/4x<br> i need help solving this please.

olganol [36]

Hi,

Work:

$\frac{2}{3x} + 6 = \frac{1}{2} + \frac{1}{4x}$

1. Move expression 1/4x to the left side and change its sign, also move constant -6 to the right side and change its sign. Now you equation looks like this:

$\frac{2}{3x} - \frac{1}{4x} = \frac{1}{2} - 6$

2. Write all numerators above the least common denominator 12x.

$\frac{5}{12x} = \frac{1}{2} - 6$

3. Calculate the difference between 1/2 and 6.

$\frac{5}{12x} = - \frac{11}{2}$

4. Simplify equation using cross multiplication.

$10 = - 132x$

5. Switch the sides of equation.

$- 132x = 10$

6. Divide both sides of equation by -132.

$x = - \frac{5}{66}$

7. Results:

$x = - \frac{5}{66} = - 0.075$

Hope this helps.
