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
Find the perimeter of the triangle with vertices D(−2, −1), E(3, 2), and F(0, 4). Do not round before calculating the perimeter. After calculating the perimeter, round your answer to the nearest tenth.
Answer: [tex]15.3\ \text{units}[/tex]
Step-by-step explanation:
Given
Coordinates of the corners are D(-2,-1), E(3,2), and F(0,4)
Length DE is
[tex]\Rightarrow DE=\sqrt{(2+1)^2+(3+2)^2}\\\Rightarrow DE=\sqrt{(3)^2+(5)^2}\\\Rightarrow DE=\sqrt{34}\ \text{units}[/tex]
Length EF is
[tex]\Rightarrow EF=\sqrt{(4-2)^2+(0-3)^2}\\\Rightarrow EF=\sqrt{(2)^2+(-3)^2}\\\Rightarrow EF=\sqrt{13}\ \text{units}[/tex]
Length FD is
[tex]\Rightarrow FD=\sqrt{(4+1)^2+(0+2)^2}\\\Rightarrow FD=\sqrt{(5)^2+(2)^2}\\\Rightarrow FD=\sqrt{29}\ \text{units}[/tex]
Perimeter of the triangle is
[tex]\Rightarrow DE+EF+FD=\sqrt{34}+\sqrt{17}+\sqrt{29}\\\Rightarrow DE+EF+FD=15.3\ \text{units}[/tex]
The diagram shows a rectangle. 5cm 1cm four of these rectangles are put together as shown, calculate the shaded area
Answer:
15 cm²
Step-by-step explanation:
5 + 1 + 1 = 7
7 × 5 = 35
5 × 1 = 5
5 + 5 + 5 + 5 = 20
35 - 20 = 15
Answer:
15 sq.cm
Step-by-step explanation:
Length of the shaded rectangle = length of the unshaded rectangle = 5 cm
Breadth of the shaded rectangle = 5 - ( 1 + 1) = 5 - 2 = 3 cm
Area of the shaded rectangle = 5 * 3 = 15 sq.cm

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25

In the figure, Z ABC and Z BCD are supplementary angles.
Answer:
x = 22
Step-by-step explanation:
line AD is 180°
so 40° + (5x + 30°) = 180°
solve for x.
5x = 180-30-40
5x= 110
x = 110/5
x= 22
Answer: 22
180 - 40 = 140
5(22) = 110
110 + 30 = 140

Answer:
For the fifth box, the correct answer is 24.
Since there are 4 different letters, use the formula 1 x 2 x 3 x 4 / {(1) (1) (1) (1)}.
When you solve that, you should get 24/1 or just 24.
Not sure if you have heard of this formula, but it is much more efficient than counting all the possible outcomes.
For the sixth box, the probability of pulling out the letters in the order of MATH is only one of the possible outcomes out of 24.
Thus, the fraction to represent this is 1/24.
Hope this clears up any misunderstandings.
