14× 14 = 196 area of 1 of the squares. on a cube there are 6 squares so multiply 196 by 6
196 × 6 = 1176 sq in
Answer: ∠ECB = 60°
Step-by-step explanation:
First, find the value of <em>x </em>by adding them up.
x + 3x + 2x = 6x
Since we know that all of the angles create a 180° angle, we can set up a proportion.
6x = 180°
To find the value of x, divide both sides by 6.
6x ÷ 6 = x
180 ÷ 6 = 30
So now the proportion is x = 30.
Now that we now x = 30, we can plug in 30 to the angle measures.
∠DCA = 30°
∠DCE = 90°
∠ECB = 60°
So angle ECB is 60°.

Using simple interest, it is found that her interest charge this month will be of $30.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
- r is the interest rate, as a decimal.
In this problem, considering the time in years, the parameters are:

Hence:

Her interest charge this month will be of $30.

All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
<h3>How to graph the inequality on a number line?</h3>
The inequality expression is given as:
2x+2/x+7 >= 0
Multiply both sides by x + y
2x+2 >= 0
Subtract 2 from both sides
2x > -2
Divide both sides by 2
x >= -1
Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
See attachment for the number line of x >= -1
