Answer:
false
Step-by-step explanation:
we study proofs in computing because it helps us to understand the mathematical computation. With the help of proofs in computing it is very easy to understand all the mathematical computation but in given statement it is given that it helps us to understand data structure so it is a false statement.
To find the perimeter of the rectangle, you would add all sides or use P=2L+2w (Perimeter = 2 times the length plus 2 times the width)
P= 2(3x-3) + 2(x-3)
P=6x-6+2x-6
P=8x-12
To find the perimeter of the triangle, add all the sides.
P=(2x-1)+2x+(2x-1)
P=6x-2
Now we know that both of the perimeters are the same so we can set them equal to each other.
8x-12 = 6x-2 solve by subtracting 6x from both sides.
2x-12 = -2 then add 12 to both sides
2x=10 last divide by 2 on both sides
x=5
Now replace x with 5 on either the rectangle or the triangle. I will use the triangle.
P=(2x-1)+2x+(2x-1)
P=(2*5-1)+2*5+(2*5-1)
P=28 feet
It’s 4 and what they said
Answer: 360
Step-by-step explanation:
The area of the bottom square is 100.
The area of each of the four triangular faces is 65.
Adding these together, we get 65(4) + 100 = 360.
Answer:
x=-9/4
Step-by-step explanation:
4x+7=-2
1) Subtract 7 from both sides:
4x=-9
2) Divide both sides by 4:
x=-9/4
