Answer:
p = 6x + 10
Step-by-step explanation:
p = 2(l + w)
p = 2(6 + (3x - 1))
Simplify terms inside parenthesis
p = 2(3x + 5)
Distribute
p = 6x + 10
Answer:
136 cm²
Step-by-step explanation:
I'm going to split the net into:
2x 7 cm by 2 cm rectangles
2x 6 cm by 7 cm rectangles
2x 6 cm by 2 cm rectangles
The 2x means there's 2 of them.
Let's find the area of the 2x 7 cm by 2 cm rectangles:
2*7*2=
4*7=
28 cm²
Let's find the area of the 2x 6 cm by 7 cm rectangles:
2*6*7=
2*42=
84 cm²
Let's find the area of the 2x 6 cm by 2 cm rectangles:
2*6*2=
12*2=
24 cm²
Adding all these areas together gives us the surface area of the net:
28+84+24=136 cm²

Answer:
C = (36/3)* $24
C = $288
Step-by-step explanation:
In this question, we are asked to write an equation for cost c of the section of fence needed for the garden and the solve for the value c.
C is already assigned as the cost of the sections she needs for her garden.
We were made to understand that the perimeter of the garden is 36 feet, with a 3 feet each section. Now, what we need to do is to know the number of sections that we have. Since, each section is 3 feet, and the total perimeter is 36 feet, this means that the total number of sections needed would be 36/3. Each of the section as we were told costs $24, so we can then proceed to calculate the value of C from there.
C = (36/3)* $24
This is the equation that gives the cost. The actual value of the cost is thus:
C = 12 * 24 = $288
The total cost of the sections if the Fence is $288
4.1 ≈ 4 inches (tenth place is less than 5, round down)
5.9 ≈ 6 inches (tenth place is more than 5, round up)
7.2 ≈ 7 inches (tenth place is less than 5, round down)
Volume = 4 x 6 x 7
Volume = 168 in³ (Answer C)
