Answer:
The new triangle will have a perimeter of 36 cm, and an area of 18 cm2.
Step-by-step explanation:
Given that the triangle whose perimeter is 12 cm and its surface is 6 cm2, and is lengthened by a scale factor of 3 to produce a similar triangle, the perimeter and surface of the new triangle arise from the following calculation:
Perimeter = 12 x 3 = 36 cm
Area = 6 x 3 = 18 cm2
Thus, the new triangle will have a perimeter of 36 cm, and an area of 18 cm2.
Answer:
35.9 units cubed
Step-by-step explanation:
Hello There!
The figure shown is a rectangular prism
The formula for volume of a rectangular prism is
Length times width times height
The dimensions for the shown figure are given
height = 4 1/2
length = 2 1/8
width = 3 3/4
given this information we just plug it in to the formula
so

then we plug it in to a calculator and get that the volume is equal to
35.859375
finally we round to the nearest tenth and get that the volume is equal to
35.9 units cubed
Answer:
8n
Step-by-step explanation:
8n is the factor of both 8 and n. in the following question.
Factor ⇒ If a number, that use to divide another number and we get zero as a remainder, the number is called the factor of another number.
In this question, 8n is divided by both 8 and n and also we get zero as a remainder.
Therefore, 8n is the factor of both 8 and n .
Answer:
It means X to the variable of m.
It would look like this:

Answer:

Step-by-step explanation:
Use the distributive property.
<u>Distributive property:</u>
<h3>
⇒ A(B+C)=AB+AC</h3>
⇒ 5*5=25
⇒ 5*8=40
<u>Rewrite the problem.</u>
⇒ 5*5a+5*8
<u>Solve.</u>
<u>Multiply.</u>
⇒ 5*5a=25a
⇒ 5*8=40
<u>Rewrite the expression.</u>
<u>⇒ = 25a+40</u>
- <u>Therefore, the correct answer is 5(5a+8).</u>
I hope this helps! Let me know if you have any questions.
