To solve this problem you must apply the proccedure shown below:
1. The perimeter of a rectangle can be calculated with the following formula:
2. The width is:
3. Now, you must substitute the values into the formula for calculate the perimeter:
Therefore, the answer is: 
∣2x+7∣ for x=-4
Use the substitution method
∣2*-4+7∣
Mutiply first then add +7
∣2*-4∣= -8
∣-8+7∣= -1
Whenever there is a negative number for absolute value , the number becomes a + positive number.
∣-1∣= 1
Answer:
1
Answer:
<h2>2.01 cm</h2>
Step-by-step explanation:
The formula of a volume of a sphere:
<em>R</em><em> - radius</em>
<em />
We have
Substitute:
<em>multiply both sides by 3</em>
<em>divide both sides by 4</em>
<em>divide both sides by π</em>
<em>use π ≈ 3.14</em>

Answer: (2.2 × 10)(1 × 10) = 2210.
Step-by-step explanation:Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So, 2.21 = (2.2 × 10)(1 × 10) = 2210.
Answer: The measurements of the two angles are 60° and 80°.
Step-by-step explanation:
A quadrilateral is a shape that has four sides and the total angle is 360°. Two angles of a quadrilateral measure 140° and 80°.
This means the two angles have a total of (140° + 80°) = 220°. We can then subtract from 360° to know the value of the other remaining angles. This will be:
= 360° - 220°
= 140°
The other two angles are in the ratio of 3:4. This means the angles are:
(3/3+4) × 140° = 3/7 × 140° = 60°
(4/3+4) × 140° = 4/7 × 140° = 80°
The measurements of the two angles are 60° and 80°.
