Answer:

x = -4

Step-by-step explanation:

Given: -2(4x + 4) - 3x - 2 = 34

To solve this equation, we have to isolate the variable. (Get x by itself).

We'll follow the PEMDAS rule as far as parentheses.

So, -2(4x + 4) - 3x - 2 = 34

= -8x - 8 - 3x - 2 = 34

Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.

Hence:

-8x - 8 - 3x - 2 = 34

+8 +2 +8 +2

-8x - 3x = 34 + 8 + 2

Now, we'll simplify.

-11x = 44

Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.

-11x = 44

-------------

-11

x = -4

. Find the area of a trapezoid with b1 = 13.8 cm, b2 = 16.8 cm, and h = 4 cm.

Ilia_Sergeevich [38]

Answer:

61.2 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h ( $b_{1}$ + $b_{2}$ )

Substitute in given values

A = $\frac{1}{2}$ × 4 × (13.8 + 16.8 ) = 2 × 30.6 = 61.2 cm²

Using rounding to estimate the solution to the problem. 538-714 Be sure to give the estimated solution, not the exact solution.

amid [387]

Answer:

1. -370

2. 70

3. 10.75

4. 6700

5. 37.26

Step-by-step explanation:

1. Estimating the solution means round the numbers to the nearest ten, then subtract the rounded numbers.

2. Same thing as #1

3. Using long division, it should be quite easy. If you need more evaluation, comment and I'll answer.

4. To the nearest hundred, you write the closest exact hundred. example: 8334 would be rounded to 8300.

5. To the nearest hundredth, you write the closest exact hundredth. example: 65.734 would be rounded to 65.73

Hope this helped, good luck!
