Answer:
92.5 centimeters.
Step-by-step explanation:
The one-meter snake showed up as 2 cm in the developed photo. Since there are 100 centimeters in a meter, you subtract the length of the snake in centimeters by the length it shows up in the picture. 100-2 is 88, so that would be the difference. To find the length of the wall, you add the difference to how it showed up in the picture. 88+4.5=92.5.
To round money to the nearest cent you would see in the ones place what that number is and if it is at or higher than 5 it would round up to 2.20
Did that help any I hope so:) if not tell me I will have another strategy
Answer:
A) it wouldn't fit
Step-by-step explanation:
Here are the pairing:
The first tile should be paired with 4th property
The second tile should be paired with the 1st property
The third tile should be paired with the 3rd property
The fourth tile should be paired with the 2nd property
Always try putting x=1 and x=-1 to see if we can find a zero.
If x=1 we get 5+8+1-2 which is not zero.
If we change the signs of the odd powers of x we get -5+8-1-2 which is zero so x=-1 is a zero and x+1 must therefore be a factor. Now we can use synthetic division to find the quadratic:
-1 | 5 8 1 -2
5 -5 -3 2
————
5 3 -2 | 0 = 5x²+3x-2 = (5x-2)(x+1).
Therefore the real zeroes are -1, 2/5, since -1 is a duplicate zero (because the cubic factorises into (5x-2)(x+1)²).
