Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
Answer:
49 is your only answer........
Step-by-step explanation:
Answer:
a view from the side.
"the parts are shown in the sectioned side view"
The volume of the case =
length x width x height
12cm x 6.5cm x 1.25cm =97.5cm^3
Answer: 20
Step-by-step explanation:
If 1 cent = 0.01 dollar
Then 5 cents = 0.05 dollar
Since 1 dollar= 100 cents
Therefore, the number of 5 cents in 100 cents is 100/5 = 20
