Step-by-step explanation:
A perimeter is when you add up all of the sides
Here would be our equation
[tex]2(x+4)+2(2x-8)[/tex]
Answer: The expression for this would be 2(x+4) + 2(2x-8)
Step-by-step explanation:
This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!

which expression has a value of 30 when x = -1 and y = 3?
Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6
= -34

How do you find the height of a rectangular prism with the volume and area?
Answer:
The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.

2x - 8x + 1 = 49
this seriously makes no sense
Answer:
x = -8
Step-by-step explanation:
2x - 8x + 1 = 49
⇒ 2x - 8x = 49 - 1
⇒ -6x = 48
⇒ x = [tex]\frac{48}{-6}[/tex]
= -8
Answer:
X = -8
Step-by-step explanation:
Add similar elements: 2x-8=6x
-6x+1=49
Subtract 1 from both sides:
-6x+1 -1 =49 - 1
Simplify:
-6x=48
Divide both sides by -6
-6x /-6= 48 /6

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Case 1: Bus
Consumption/ 100Km= 301
and, for 250 Km= 301 /100 x 250
= 751
Case 2: Car
Total = 80 people
Total cars= 30/5 = 6
Consumption/ 100Km= 91
and, for 250 Km= 91 /100 x 250
= 22.51
Consumption by 6 cars = 6 x 22.51 = 1351
Difference between Gasoline Consumption = 1351-751 = 601
