1. Answer: x=36
because you first multiply both sides by 3 then reduce the numbers with the greatest common factor 3. Then you multiply the number and get 36.

2. Answer: x= -2 and x=2
Divide both side of the equation by 3. Take the square root of both sides of the equation and remember to use both positive and negative roots. Then separate the solutions.

3. Answer: x =∛12 or 2.28943 in alternate form

Take the root of both side of the equation

4. Answer: 1728
Raise both sides of the equation to the power of 3. Then reduce the index of the radical and exponent with 3. Evaluate the power.

5. Answer: 48
Square both sides of the equation. Divide both sides of the equation by 3.

6. Answer: 1/4
Determine the defined range. Multiply both side of the equation by x. Swap the sides of the equation. Divide both sides of the equation by 12.

Trigonometry

The area of the triangle PQR is 17.6 square units.

Explanation:

Given that the sides of the triangle are PQ = 12 and PR = 3 and $m\angle P = 78^{\circ}$

We need to determine the area of the triangle PQR

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$\text {Area}=\frac{1}{2} qr \sin P$

Substituting the values, we get,

$\text {Area}=\frac{1}{2}(12)(3) \sin 78$

Simplifying, we have,

$\text {Area}=\frac{1}{2}(36)(0.98)$

Multiplying the terms, we have,

$\text {Area}=\frac{35.28}{2}$

Dividing, we get,

$\text {Area}=17.64$

Rounding off to the nearest tenth, we have,

$Area=17.6$

Thus, the area of the triangle PQR is 17.6 square units.

Andrei [34K]

Let x = times in the pool
Let y = times in the basketball courts

42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x

The person used the pool 9 times.
