Answer:
(4x + 22) feet
Step-by-step explanation:
Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?
A patio deck = Rectangular in shape
Hence:
The formula for the Perimeter of a rectangle = 2L + 2W
Where
L = Length
W = Width
The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet.
The perimeter of the deck =
2(x + 8)feet + 2(x + 3)feet
= (2x + 16) feet +( 2x + 6)feet
= (2x + 2x + 16 + 6) feet
= (4x + 22) feet
Therefore, the perimeter of the deck = (4x + 22) feet
Answer:
d = 18
Step-by-step explanation:
a = 3;
therefore
d = 4a + 6
d = 4(3)+ 6
d = 12 + 6
d = 18
Answer:
option B)
x = 2
Step-by-step explanation:
Given in the question the equation:
10x - 3(x- 6) = x + 30
Simplify the left side
10x - 3(x - 6) = x + 30
10x - 3x + 18 = x + 30
rearrange the terms and containing x to the left side of the equation and add accordingly
x(10 - 3 - 1) = (30 - 18)
x(10 - 4) = (12)
x(6) = 12
6x = 12
Divide each term by 6 and simplify
x = 12/6
x = 2
