I can find the perimeter and area of the rectangle
2 answers:
Answer:
Step-by-step explanation:
To find the perimeter (P), add up all of the side lengths of the figure:
(numbers in parenthesis are the unlabeled values in the figure).
To find the area of the figure (A), multiply the length and width of the original rectangle . Then, subtract this amount (84) minus the area of the missing rectangle in the top left corner
.
Subtract the required values: .
<u>Therefore, the perimeter of the figure is 38 units, and the area of the figure is 72 units.</u>

Steps of adding 7+(-10) using number line are as following:
1) Draw a number line by ranging from -10 to +10.
2) Point out 7 on the number line.
3) Because -10 is added to 7 on the number line, please move 10 numbers left to 7 on the number line. We always go left in addition of a negative number on the number line.
4) The number we reach -3 on left side would be our final sum.
5) From the number we can clearly see that moving 10 number on left to 7, we get -3.
Note: We are moving left because of negative sign in front of 10.
Answer:
1. Distributive property.
2. Combining like terms.
3. Addition property of equality.
4. Division property of equality.
Step-by-step explanation:
- The Distributive property states that:
- The Addition property of equality states that:
- The Subtraction property of equality states that:
- The Multiplication property of equality states that:
- The Division property of equality states that:
Given the following equation:
We can identify that the methods Maria used to solve it and the order, are:
1. Distributive property:
2. Combining (or adding) like terms:
3. Addition property of equality, because she added 36 to both sides of the equation:
4. Division property of equality, because she divided both sides of the equation by 12:
Answer:
90°, 60°, and 30°
60°.
Step-by-step explanation:
The triangle ABC has side lengths √6, √2, and 2√2 units.
It is clear that the triangle ABC is right triangle because (2√2)² = (√6)² + (√2)² that means the side lengths satisfy the Pythagoras Theorem.
Now, if the angle between hypotenuse (2√2 units) and base (√2 units) is , then
Hence, = 60°
Therefore, the three angles of the triangle are 90°, 60°, and 30°.
Now, if the base of the triangle is 16 units, then other two side lengths will also change proportionally to remain the triangle a right triangle.
And in that case the base angle will remain 60°. (Answer)
