Answer:
54cm
Step-by-step explanation:
because a trangle is half of a square so you have to mutiple by 2 so 27 * 2 = 54 :)
Answer:
x = -9
Step-by-step explanation:
The top angle would be 90 degrees due to the square.
The angles of a triangle add up to 180 degrees.
Set up the equation:
90 + 45 + x + 54 = 180
189 + x = 180
Subtract 189 from both sides:
x = -9
Now, if you need to solve for the angle, just plug x in:
-9 + 54 = 45 degrees
(In your case it is just looking for x so it would be x = -9)
Formula for the perimeter of a rectangle = 2(L + W).
let the width be x
length = 2 + 2x
substitute respectively
52 = 2(2 + 2x + x)
52 = 2 (2 + 3x)
52 = 4 + 6x
52 - 4 = 6x
48 = 6x
divide both sides by 6
48/6 = 6x/6
8 = x
width = 8
length = 2 + 2x = 2 + 2(8) = 2 + 16 = 18
Answer:
-7
Step-by-step explanation:
Coefficients are the numbers that multiply the following variables, so in the case of -7yz^2, the coefficient would have to be -7.
Answer: A) and B)
Step-by-step explanation:
So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.
The second one you find the distance it moves each second.
You do this by distance over time d/t. Then you divide the 408 by that number.
So 264cm / 11 seconds = 24 cm/sec
Then 408cm/ 24cm per sec = 17s
